SATELLITE DISH Suppose the receiver in a parabolic dish antenna is 2 feet
from the vertex and is located at the focus. Assume that the vertex is at the
origin and that the dish is pointed upward. Find an equation that models a
cross section of the dish.
a. x2 = -8y
b. x2 = 2y
c. x2 = 8y
d. y2 = 8x
Answers: 2
where 
is the vertex of the parabola and 
is the focus point. Since we are given that the receiver is 2 feet above the vertex which is located at the focus point and the vertex is 
at the origin, then the focus point is 
where 
. Therefore, the equation that models a cross section of the dish is 
.
