This is a quick set of notes to go over the transformations that can happen to a linear function. It includes f(x) +/- k, f(x +/- k), kf(x), f(kx), -f(x) and f(-x). I couldn't find any basic notes anywhere on the internet so I created a very quick table to use in unison with Desmos where we would actually look at various linear functions and what happens to them.
