A satellite dish is being designed so that it can pick up radio waves coming from space. The satellite dish will be in the shape of a parabola and will be positioned above the ground such that its focus is 50 ft above the ground. Using the ground as the x-axis, where should the base of the satellite be positioned? Which equation best describes the equation of the satellite?

A. (0, 25); y = one over one hundredx^2 − 25
B. (0, 50); y = one over two hundredx^2 − 50
C. (0, 25); y = one over one hundredx^2 + 25
D. (0, 50); y = one over two hundredx2 + 50

please give an explanation (optional) if you can so I can understand. thank you!!
