Question

Franco is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satellite can be modeled by mc024-1.jpg, where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?

Answer 1

y^2+6y = 3x-3
(y+3)^2 = 3(x+2)
So, its focus is at

(x+2) = 3/4
x = -5/4

Answer 2

the answer is b (-1.25,-3)
