Which is one of the transformations applied to the graph of f (x) = x^2 to change it into the graph of g (x) = 4x^2+24x*30?

Changing g (x) to this form: a (x-h) + k, we have:

g (x) = 4 (x+3) ^2 - 6

Comparing this to the original equation, f (x) = x^2, we have the following transformations:

The graph is widened.

The graph is shifted left 3 units.
