Write the equation of the parabola in vertex form. The vertex is (-3,-4) and the parabola passes through The point (-1,0).

y + 4 = (x - h)^2

Step-by-step explanation:

"vertex form" is y - k = a(x - h)^2.  Here, the vertex (h, k) is (-3, -4), and so we have:  

y + 4 = a(x + 3)^2.  To find the coefficient a, substitute -1 for x and 0 for y:

0 + 4 = a(-1 + 3)^2, or

4 = a(2^2).  Thus, a = 1, and the desired equation is

y + 4 = (x - h)^2
