A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror. The pipe is located 2 inches from the vertex of the mirror. Write an equation of the parabola that models the cross section of the mirror. Assume that the parabola opens upward.
***
equation of a parabola that opens upward with vertex at the origin: x^2=4py
p=2 (distance from vertex to focus)
4p=4
equation: x^2=4y
