Cube Root Functions
2
Where does a cube root function come from?
Look at the cubic function to the right. To find the inverse, switch the x column with the y column.
3
Good news!
We don't have to worry about restricting any domain here because when we switch our x and y columns, we still have a function! The domain and range of both a cubic function and a cube root function are all real numbers.

How do we find the inverse of a cubic function algebraically?
Same as any function- switch x and y and solve for y.
11
When you find an inverse, remember to use inverse operations starting on the outside.
