This is how to solve the problem: "What is the transformations of f(x)=(x-2)^2-4"
Looking at the quadratic equation given, f(x) = (x-2)^2 - 4 It's like seeing product of sum and difference of two squares. (x-2)^2 - 4 [ (x-2) - 2 ] [ (x-2) + 2 ] [ x - 2 - 2 ] [ x - 2 + 2 ] [ x - 4 ] [ x ] [ x^2 - 4x ] So the final transformation of f(x) = (x-2)^2 -4 is f(x) = (x^2 - 4x). In this way, we are able to show how a complicated equation to simple yet equal equation in quadratic form.
