    sooo, i have a math test tomorrow. and it's on transformations and quadratic functions.. i just need some clarification on what these (a, k, and h) terms mean.. i'm referring to the equation g(x) = a(x-h) +k h is a horizontal transltion (left or right) k is a vertical translation (up or down) .. but i don't understand what a is.. it supposed to be a "vertical stretch or compression" but what does that mean? and how can i apply that to the graph?
