The first set of functions I used were to make the hair. To make the hair I used a quadratic function. I made x negative so the line would flip and I added a slider to each function so I could make it more narrow or more wide. I then restricted the domain so that the hair would stop at the point I wanted.
The next set of functions I used were to make the eyes. The smaller circle of the eye is originally (x+1)^2 + (y-2)^2< .1 and I changed the .1 to .3 to make the outer eye bigger than the inner.
The function I used is a constant function for the eyebrows. I set y equal to the point I wanted them on the graph and restricted the domain. I did the same to finish off the smile.
The last thing I did was make a mustache using quadratic functions. I made x negative and added a slider to each line to made them different widths. I then restricted the domain so it would stop at the length I wanted.
At first I found that changing around the functions to make a face was challenging but after I went over all the kinds of functions I found that it was easier. One thing I learned is how to restrict the domain and range.
