Question

I WILL AWARD A MEDAL

Derive the equation of the parabola with a focus at (−7, 5) and a directrix of y = −11.

f(x) = 1/32(x + 7)^2 − 3

f(x) = −1/32(x + 7)^2 − 3

f(x) = −1/32(x − 7)^2 − 3

f(x) = 1/32(x − 7)^2 − 3

I think maybe B

Answer 1

its b it must be because it fits better

Answer 2

i am not super certain tho

Answer 3
