You can see how the original input a, produces b through f(x). THEN, b is used as the input to f^-1(x) to BACK to a.

​4 steps to find inverse function

•Step1: Let f(x) = y

•Step 2: Interchange x and y

•Step 3: Solve for y

•Step 4: Change y to f^-1(x)

​Find the inverse of the following function: f(x) = x -3

Said another way...

• x's are inputs

• f(x) are the corresponding outputs

• So...f^-1(x) can take the outputs and reproduce the corresponding inputs

• Inverse functions take you back to where you started.
