Question

help please :(

Derive the equation of the parabola with a focus at (-5, 5) and a directrix of y = -1

f(x) = - (x - 5)^2 + 2
f(x) = (x - 5)^2 + 2
f(x) = - (x + 5)^2 + 2
f(x) = (x + 5)^2

Answer 1

you need to find vertex

Answer 2

can u draw the parabola roughly... based on given focus and directrix ?
