Answer: y= -(x+2)^2-4
Explanation:
(In photo too)
The equation of a parabola as seen here needs to be in Vertex form which is
y= a(x-h)^2+k where a= concave up or down and (h,k) is the vertex. Here the vertex is given of (-2,-4) so you just plug in. And the A here would be negative one because it concaves down
