Scaling and Stretching Quadratics - Expii

To stretch or compress vertically, replace y = f(x) with y = cf(x). To compress or stretch horizontally, replace y = f(x) with y = f(cx). To reflect (vertically) about the horizontal x-axis, replace y = f(x) with y = -f(x). To reflect (horizontally) about the vertical y-axis, replace y = f(x) with y = f(-x).
