The vertex of the parabola below is at the point (-3, -5). which of the equations below could be the one for this parabola? A. x = -3(y + 5)^2

B. y = (x + 3)^2 -5

C. y = (x - 5)^2 + 3

D. y = (x + 3)^2 + 5

Step-by-step explanation:

The coordinates of a vertex are (h, k). If our vertex is (-3, -5), then h = -3 and k = -5. The vertex form of a parabola is

so if we fill in our h and k values, the equation becomes

and, simplified, is
