Hi,
*Note:the vertex form of a parabola, {{{y=a(x-h)^2 +k}}} where(h,k) is the vertex
The vertex of this parabola is at (-2, -3)
y = a(x+2)^2 - 3
Ordered pair Pt(-1,-5)is on the parabola
-5 = a(-1+2)^2 - 3
solving for a
-2 = a(1)^2
-2 = a, the coefficient of the squared expression
y = -2(x+2)^2 - 3
