I'm having difficulty with this question. All help is appreciated.
*The cross section of television antenna dish is a parabola and the receiver is located at the focus.
A. If the receiver is located 5 feet above the vertex, assume the vertex is the origin, find an equation for the cross section of the dish.
Okay, I know the vertex is 0,0. The focus is 0, 5. The equation is x^2=4ay.
I don't know where to go from there, or what equation is needed to find the cross section.
