Answer: Choice B) y = (x+4)^2 - 1

-------------------------------------------------------------------

Reasoning:

The vertex is (h,k) = (-4,-1) so h = -4 and k = -1

In each answer choice, a = 1. 

Plug a = 1, h = -4 and k = -1 into the equation below and simplify

y = a(x-h)^2 + k
y = 1(x-(-4))^2 + (-1)
y = (x+4)^2 - 1
