If you are not sure what an inverse function is or how to find one then this video should hopefully show you.

Example:

In this tutorial you will be shown how to find the inverse of the following:

- If f(x) = (3x – 2) / 8, find f
^{– 1}(x)

## Inverse Example on Handling more than 1 ‘x’ term.

In this example the aim is to have two *x* values in the function and show that you can use other letters other than *f(x)*

Example:

- If g(x) = (2x – 3) / (x – 1), x ε ℝ, x ≠ 1, Find g
^{-1}(x)

## Inverse Example involving Exponential Functions

In the next example you are given an exponential function and introduced to using other notation.

Example:

- If h: x ↦ e
^{(2x + 1)}find h^{– 1}

## Inverse Examples using Natural Logs

In this example you are given a function using natural logs and asked to find the inverse.

Example:

- If f(x) = 2 ln(3x – 1), x > 1/3. Find f
^{– 1}(x).
