September 11 - Inverse functions

The topic for today was inverse functions.

The inverse of a given function, f(x), is derived by taking the order pairs that make up f(x) and switching the inputs and outputs. So if (a, b) is a point on f(x), then (b, a) is a point on the inverse of f(x).

Note the inverse of a function might not be a function. No biggie.
