Answers
You should be familiar with the vertex form of a parabola
y =a(x-p)^2 + q , with vertex (p,q)
so for yours, vertex is (-4,2) , so
y = a(x+4)^2 + 2
sub in (-3.0)
0 = a(1)^2 + 2
a = -2
y = -2(x+4)^2 + 2
y =a(x-p)^2 + q , with vertex (p,q)
so for yours, vertex is (-4,2) , so
y = a(x+4)^2 + 2
sub in (-3.0)
0 = a(1)^2 + 2
a = -2
y = -2(x+4)^2 + 2
