Find the equation for the following parabola.
Vertex (-2,-4)
Focus (-4,-4)
A. (7-4)2 = -8(x-2)
B. (x+4)2 = 8(y+2)
C. (y+4)2 = 8(x+2)
D. (y+4)2 = -8(x+2)

, option D.

Step-by-step explanation:

Equation of a parabola:

The equation of a parabola has the following format:

In which the center is (h,k) and the focus is (h+p,k).

Vertex (-2,-4)

This means that

So

Vertex (-2,-4)

Focus (-4,-4)

-4 - (-2) = -4 + 2 = -2

So p = -2 and

, option D.

3; 9 is 8 to -4

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
