Reminders about Inverse Functions:
1) A function has in an inverse if it is one-to-one (passes the horizontal line test).
2) Inverse functions trade their domain and range.
3) The inverse of f(x) is denoted f-¹(x).
4) Two functions are inverses if their composite functions are:
f (ƒ-¹(x)) = f¹ (f(x)) = x
