Domain is the set of all x-values Range is the set of all y-values To find the y-intercept on the graphing calculator; hit Trace, type 0, and hit Enter. The answer will then come up onto the screen. To find the x-intercept(s) on the graphing calculator; hit 2nd Trace, choose option 2:Zero, then move you cursor left of one x-intercept and hit Enter, then move your cursor right of one x-intercept and hit Enter, then make you guess as to where the x-intercept is and hit Enter once more. The answer will then come up onto the screen. Repeat as needed for other x-intercepts. To calculate minimums on the graphing calculator; hit 2nd Trace, choose option 3:minimum, move your cursor left of the turning point and hit Enter, move your cursor right of the turning point and hit Enter, and hit Enter once more. The answer to what the minimum is will show up on the screen. To calculate maximums on the graphing calculator; hit 2nd Trace, choose option 4:maximum, move your cursor left of the turning point and hit Enter, move your cursor right of the turning point and hit Enter, and hit Enter once more. The answer to what the maximum is will show up on the screen. To find the intersection point of two functions type them into Y=, then hit Graph, then click 2nd Trace, then choose 5:intersect, Click Enter 2 times, then get your cursor close to the intersection point and hit Enter one last time. The intersection point should then show up on your screen. To view the table of a function click Graph first, then click 2nd Graph. Now you will be able to see a table of that graph/function. To view a split screen of the table and the graph of a function you need to; hit Mode, scroll down to where is says FULL, then click the arrow over to the Graph-Table and hit Enter on it. Then click the Graph button to see the split screen. To move on the table and see those values click Trace. To move on the graph instead click 2nd Graph. Sometimes the graphing calculator gives you error messages, to avoid this make sure that all of your negative numbers have the negative sign instead of the subtraction sign. This can be easy to mess up, so just double check you got the whole equation written into the calculator the right way.

Lately on Desmos we have been working with functions and "parent functions". Parent functions are the starting point of all other equations you could make using these as a place to base your function on. The functions we have learned about are: f(x)=x f(x)=x^2 f(x)=x^3 f(x)=|x| f(x)=√x To make a function move up or down you just need to add or subtact the number away from the origin it is from the function. You need to do this OUTSIDE the parent. Here are 2 examples of this for each function: y=|x|+2 y=x^2+2 y=√x +2 y=x^3+2 y=x+2 .....To move UP y=|x|-2 y=x^2-2 y=√x -2 y=x^3-2 y=x-2 ..... To move DOWN To make a function move left or right you just need to add or subtract the number away from the origin it is from the function. You need to do this INSIDE the parent. Also, take note of "left right lies" To move left you add, and to move right you subtract. Here are 2 examples of this for each function: y=|x+2| y=(x+2)^2 y=√(x+2) y=(x+2)^3 y=(x+2) ..... To move LEFT y=|x-2| y=(x-2)^2 y=√(x-2) y=(x-2)^3 y=(x-2) ...... To move RIGHT To make a function steeper or less steep you need to multiply. To make it steeper you multiply by a number greater than 1. To make it less steep you multiply by a number between 0 and 1. Here are 2 examples of this using the y=x parent: y=2x.....STEEPER y=.25x.......LESS STEEP Now as a final example I will show you how to make a V shape steeper, left 2 and down 4. You start with the parent function y=|x| because this function makes the shape of a V. Then to make it steep you multiply the X by 4 let's say. Then to go left 2 you need to add 2 inside the absolute value lines. Finally to go down 4 you need to subtract 4 from the outside of the absolute value lines. Your equation should come out like this and the graph that goes with this equation looks like this: y=4|x+2|-4
desmos.com Desmos is a free website that is a graphing calculator. In this I will tell you how to do some of the things Desmos offers. When you get to desmos it will look like this: To make an equation into a table, you need to first type your equation into the left side area. Then click on the gear that is in the top right hand corner of the typing area, then click the symbol that looks like a table after this to create your table. Then you can edit the table as you need to. To find an intersection point find where the two line intersect, click on your graphed line at that point, then read the coordinates. To send a screenshot you will need to make an account. I did so by connecting desmos to my google account. Once you've done this you click on the green button to the right at the top. This will then open up like so: You can choose any way to share it but if you select image it will open a new tab where you can download the screenshot of your graph and email it, share it, or save it to your computer.
In Algebra Lab and we learned how to use gmath. Gmath is a program that allows you to create math expressions/equations with graphs, handwriting, speaking, and typing. To add gmath to your computer you will need to create a google doc, scroll over add-ons, put your mouse over g(math), then select create math expressions. Then you will will be able to get the program running, a tutorial will also come up; watch it! Next once you have typed an expression or equation you press the button to the left that looks like this: To use the handwriting option go back to add-ons, scroll over g(math) and then select create a handwriting entry. Then a new window will pop up, here you can write with your mouse to create a math expression or equation.
If you would like to use factions, exponents, etc. in your math equation go back to create math expressions, click advanced, then click the icon that shows x^a this will then give you a bunch of options to choose from. This is how to add these by typing and not talking through the microphone or handwriting it. In order to create a graph you will need to once again scroll over add-ons, click g(math), and select create a graph. Now from here type your equation/expression into the box that says functions. After this feel free to change your graph zoom region as you wish, and then click insert to doc when you are ready. In my personal opinion I think gmath will be very helpful to me in the future especially since Chromebooks are being used more and more in the classroom. It is easy to use (except for the microphone part), and it makes writing expressions/equations on the computer a breeze. Today is our last digital literacy class. Next week we begin Algebra Lab. As this is our last class, a final reflection is needed. One of the most important things in Digital Literacy that I have learned is how to be a good digital citizen. Out of all of the activities, assignments, and projects we did I most enjoyed the country researching project because I required us to one learn how to make a good presentation and two because it was something I was interested in. I didn't really like coding. I found it to be boring and a waste of my time. I think that I will be using NoodleTools and Prezi in my future classes because they will be most useful to me. The playlists that we used helped to create a learning plan and to keep everyone on track, but some of the things on the playlists I already knew and didn't need to spend a long amount of time on. The overall class felt really slow to me. It felt like we were doing the same thing every day and accomplishing not as much as I would in my other classes. The screencast videos were helpful to some degree. They didn't teach us everything we needed to know though about what we were doing. Overall, I wish if I was to take this class again that it wasn't as slow. I understand some people like the slower pace, but for me I like to work at my own pace (which is pretty fast) so this wasn't ideal for me
Padlet was cool, but since we didn't use it often I felt like I didn't get enough knowledge about it to make an opinion about it. The blog questions we did at the beginning of the year certainly helped with this blog, but I felt like we never focused on making our blogs really good. The blog don'ts I felt were important to know, but we just kept going over them that half of the things we did with the blog don'ts weren't necessary. The social media and your future playlist I felt was one of the most important things I learned in this class. Same thing with the college bound activity. It really opened my eyes to the real world. The digital citizen project was not needed as we already knew everything and no research was needed. We could of used popplet, google slides, and screencast for another project that was more interesting to us. Everything about the licensing was important to learn and I didn't really know a lot about it so it expanded my knowledge. I really like the country research project and everything we learned doing it. And finally as I have said before I didn't like coding. Although I didn't like some of the digital tools we used I am glad I was able to learn how to use them. They will definitely help me in the future. ![]() Today in class we learned to code some more. We used the website Code.org which provides things called "Hour of Code" where in less than an hour you can learn to do simple coding. When we first started this assignment, I choose to do the Minecraft hour of code. I successfully completed it. Today, I first started off by doing the hour of code called artist, this was too hard and confusing for me though so I gave up on it. I finally ended up choosing the Infinity Play Lab. This one was easy to understand and complete. For the end the "game" a created was for the user to have a character touch another character by using the arrow keys. I learned that coding is a valuable thing to learn, if you want to program different things. I must admit, it was pretty cool being able to move a character around on the screen by myself however, I don't really like to code. I find it time consuming and sort of boring and hard to understand. This for me was the most challenging part of getting through this assignment. In the future I don't think I will be coding as it has no interest to me, but maybe another teacher will assign this work to me and then this information will be used. For a while now we have been working on creating a project in Prezi about a country. As you know Casey and I have chosen Sweden as our country of topic. Since then we have created a Prezi, added information, audio, and pictures. Right now we are beginning the final stages of our project. We still need to find a TouTube video to include in the Prezi and a few more pictures, plus a work cited "slide". If you don't know what Prezi is, it is a program that is like Microsoft powerpoint or google slides in the sense of being able to present information, but Prezi doesn't really have "slides". Instead Prezi has a big picture look at all of the information that you can then zoom in on in order to see the information being presented more clearly (if that makes any sense).
Prezi allows you to make anything "zoomable". This I found very interesting and cool. We were able to rotate text and then zoom in on it to see it in a straighter way. This isn't as easy to understand without seeing it tough. It was a little difficult to arrange the text in a way that flows, but in the end Casey and I found a good way to go from point to point. In the future I will be able to use Prezi in order to create more dynamic presentation to capture the audiences attention. Update 10/26/16: Here is a picture of our finished Prezi We have since moved on from fair use and onto another project about a country. My partner Casey and I chose Sweden as our country. To research this country we have used CulturalGrams, Britannica, and World Book to gain information on Sweden. They are all online databases that our school has subscribed to. I like how in CultureGrams you can click on the different tabs of information so it is more organized and easier to read. Britannica on the other hand has one page of information that you have to scroll through. This isn't as convenient and nice to read. After we found our information we put it into NoodleTools. We created note cards on NoodleTools to take down important information. At first I was hesitate towards this because I like to take notes by hand, but as it turns out taking notes on the computer is easier for this project.
Today in class we were put into groups to work on an assignment about fair use. For this we had to watch a video that Professor Faden did using Disney movies to create an educational video about fair use. We then went over the guidelines for fair use to decide if he used Disney's movies in a legal and correct way. These guidelines include:
The difficult part of this assignment (even though this wasn't really needed) was understanding the video. Comprehending what they were saying was a little difficult since they were multiple videos cut and edited together. This assignment was interesting because we were able to see exactly what makes something fair use and how to determine if it was in fact fair use. This information will be helpful to me in my future. It will be helpful because I will know how to judge my future school projects and essays to see if they are fair use. With these guidelines I will never be found in a legal battle over copyright. ![]() Fall Leaves by Kaitlin C. is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
