Suppose you are using a computer to draw a face on a coordinate plane. The eyes are at (-3,3) and (3,3).

The tip of the nose is at the origin. To make a smiling mouth, you are going to enter the equation for the graph of a quadratic function, with its appropriate domain.

Post the quadratic function that you would use (in any form) with the domain. Explain how you determined your equation and why you wrote it in the form that you did.

A. Choose a smile function from another student. Discuss how their graph compares to your graph. Tell how you can see these differences by analyzing the equations.

B. If someone chooses your smile function for a comparison, tell if you agree or disagree with their discussion, and why.
