This course is fundamentally an exploration of various algebraic functions, and we often have examined the inverse of those functions. In essence, a function takes in a domain element, performs some operations (generally specific to that function type), and produces a corresponding range element. The inverse of that function, as the name implies, returns to the starting point: if the inverse of a function exists, for every function pair, (x,y), there is an inverse function pair, (y,x).
