Can u me with this algebra question

The parent function for quadratic equations is as followed:



where a for vertical stretches, b is for horizontal stretches, h is the x value of the vertex, and k is the y value of the vertex.

The vertex of the is (-3, -2), so we can write the first part of the equation:



To determine if the graph has any stretches, we can check how changes to the x coordinate affect the y value. If there  are no stretches, as the x coordinate moves away from the vertex, the y coordinate should be x^2 from the vertex. If we test with a couple points on the graph, wee see that this is true, so there are no stretches. The answer is:
