How do I find the vertical/horizontal compression/stretch?

For the graph, determine the equation of the function in the form y=a(x-h)^2+k. Then describe the transformations that were applied to y=x^2 to obtain the graph.

Here is the graph:

I got reflected in x-axis and vertical shift by 2 (UP 2)

However, I don't know how to find the vertical/horizontal compression/stretch?
