Find the Inverse of a Linear Function #Shorts

How to find the inverse of a linear function. Begin by replacing the function notation f(x) by y. Find the inverse by switching the x and y values. The new y is the inverse of the original function.

Steps for actually finding inverse functions.
Step 1: Replace f(x) with y.
Step 2: Interchange x and y.
Step 3: Solve the resulting equation for y.
Step 4: Replace y with the notation for the inverse of f.
Step 5: (Optional) Verify that the functions are inverses.
