- Besides the functions used in the original image, I added six other functions. I used the absolute value function to provide a beard for my smiley face, I utilized the quadratic function to give my smiley face hair, the cosine function was used to give the smiley face a proper moustache, and the vertical and horizontal functions were used to make a hat to put on the head of the smiley face.
- Many adjustments needed to be made in order to make my smiley face look as normal as possible. When I used the cosine functions, I added five outside of the absolute value signs so it would move up five spaces and be on the proper spot on the face. I also had to put brackets in to adjust the endpoints. For the quadratic function I utilized the slider tool as much as possible. I moved the parabola up, widened it, and changed the direction it was going. When I used the horizontal and vertical functions, I had to make a hat. I had to use the brackets to tell the lines when to end. I also had to shift them up and down to make sure they were in the right place.
- What I found challenging was trying to figure out what would change what when using the functions. I wasn’t sure what I should add or subtract in order to make the changes I wanted. I now have a better understanding of what I need to do if I want to do things such as move the image on the graph upwards or downwards, sideways, or flip across the axis.
