Answer:

y =2(x+3)^2 -3

Explanation:

The vertex form of a parabola is written

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

where (h,k) is the vertex

The vertex from the graph is (-3,-3)

y = a(x--3)^2 -3

y = a(x+3)^2 -3

We can use the other point to determine a

(-5,5)

5 = a(-5+3)^2 -3

5 =a(-2)^2 -3

5 =a4 -3

Add 3 to each side

5+3 = 4a -3+3

8 = 4a

Divide by 4

8/4 = 4a/4

2 =a

y =2(x+3)^2 -3
