Find the equation of the parabola with a directrix of y = -4 and a focus of (4,8).

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

answer: c

step-by-step explanation

this isn't considered a conic so to find these properties are dfficult.

the vertex: is unknown but you can use the vertex form to figure out (y-4)^2 = 24. this would you find both the focus and directrix.
