(Section 1.9: Inverses of One-to-One Functions) 1.9.11Mechanical Approach to Finding the Inverse of a One-to-One FunctionfGiven a formula forfin terms of x, we can attempt to find a formula for f±1as follows: Step 1: Replace fx()with y. Step 2: Switch xand y. (Remember the theme of switching inputs with outputs.) Step 3: Solve for y, if possible. Step 4: Replace ywith f±1x. Step 5: If necessary, impose restrictions and ensure that Dom
