All that does is shift the vertex of a parabola to a point (h,k) and changes the speed at which the parabola curves by a factor of a ( if a is negative, reflect across x axis, if a=0 < a < 1, then the parabola will be wider than the parent function by a factor of a, if a = 1, the parabola will be the same shape as the parent function but translated. And if I focus on the vertex of f, it looks like if I shift that to the right by three, and then if I were to shift that down by four, at least our vertices would overlap.
