HORIZONTAL LINE TEST: It is used to determine if there is and inverse.
STEPS TO FINDING AN INVERSE:
1) Use the horizontal line test to determine if it has and inverse.
2) In f(x), replace with f(y) and then interchange x and y.
3) Solve for y.....Write f^-1(x) in the new equation.
4) State any restrictions.
