Answer:
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
