Question

What is the equation of the parabola, in vertex form, with vertex at (-2,-4) and

Answer 1

Answer:

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

$(y-k)^2=4p(x-h)$ and h and k are the coordinates of the vertex. Filling in:

$(y+4)^2=4(4)(x+2)$ which simplifies to

$(y+4)^2=16(x+2)$ choice C
