the headlights on a car work opposite to the way in which the television dish antenna works. The headlight bulb is at the focus of a parabolic reflector behind it. The bulb is 1.5 inches from the vertex of the reflector. Find an equation of a cross section of the reflector. The reflector is 6 inches wide. Hope deep is it?
