This problem can be solved by examining what you are given. You're given -(x+2)^2-4. The problem that you are given is in vertex form. a(x-h)^2+k. a shows direction and intensity of the curve. x is your x value, h is the opposite of the x value for the vertex, and k is your y value for the vertex. What this shows is that the graph opens downward due to the negative value for "a"). The vertex is (-2, -4).

Opens downward
Vertex: (-2,-4)
