Question

The vertex of the parabola below is at the point (-3, -5). which of the equations below could be the one for this parabola?

Answer 1

Answer:

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

$y=(x-h)^2+k$ so if we fill in our h and k values, the equation becomes

$y=(x-(-3))^2+(-5)$ and, simplified, is

$y=(x+3)^2-5$

Choice B.
