Question

HURRY! 50 POINTS!

Answer 1

Answer:

Option A , (0, 20); y equals one over eighty times x squared plus 20

Step-by-step explanation:The equation of parabola is given by  

(X-h)^2 = 4p(Y-k)^2

In this case h = 0

So we get  

Y = X^2/4P +k

Focus point is (h, p+k) , p+k = 40

Hence h, k = (0,20)

P = 40-k = 20

Equation Y = X^2/80 +20

Hence, option A is correct
