If moving the vertex to the right makes it (x-3), why, when I move the vertex down four, doesn't the equation then equal (x-3)+4? 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.
