Desmos Art Functions Card 2023
1) how you figured out what equations to use?
- Before I drew the line, I observed the shape of the part I wanted to work on and write down a few different types of functions to compare which one perfectly fit.
(2) Did you have any challenges?
- I had a lot of challenges throughout the whole process. The line of the function did not go the way that I want, so I needed to keep changing numbers and try. And the one line in the image would use a couple of functions to make.
(3) Any aha moments?
- I figured out that all the places I got stuck can use the radical function. And when I tried to fill in the color, always had errors then found out that I mark a bunch of functions with the same numbers.
(4) Did you get help?
- Yes, when I got to struggle with things, I asked the teacher.
(5) Did you use any strategies?
- I would say not the strategies, but the experiences, when I worked on the half-last part of the picture, I felt my speed was faster and could decide which kind of function would fit different lines.
(6) How did this assignment help you understand more about transformations of functions and relations?
- Before doing this project, I only knew the shapes of functions and their names. But doing this project, I needed to create the functions by myself and also at the time needed to move them to the place I need. Through the project, I had a better understanding of transformation and expanding functions and also had a clear thinking of different types of functions. Overall, the project helped me have a deeper understanding of functions on the application side.

I used only x of the required types |

Function notation (30 marks) |
|

10 |
I used function notation a few times to transform the same function repeatedly. |
|
|
0 |
I wrote new equations every single time and did not use function notation. |

Creativity and Complexity of Functions & Relations (30 marks) |
|
|
30 |
My equations show complexity and creativity. I used multiple transformations. (Stretches, Reflections, Translations, Inverses). I made excellent use of domain and/or range restrictions. I combined functions from different units. |
30 |
|
15 |
I used mostly the same type of functions, with some transformations. My functions sometimes overlap because I could not figure out the correct domain and/or range. |
|
|
10 |
My equations lack complexity and creativity. |
