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).
