Take the cube root of both sides of the equation.
Alternative to @Mark44 's fine suggestion:
You could use the "DrawInv" function.
To do this, suppose you have Y1=X^3 as a function to be graphed.
Go to the main screen.
To graph the in verse of Y1, you will need to have your display screen show: "DrawInv Y1".
If you know how to do this, fine. Press "ENTER".

Else:
Go to the "DRAW" menu: (2nd - PRGM) and pick item 8, which is DrawInv .​
Next: Look under "VARS", you need the ""Y-VARS" option. The first option under that is "Function ... ", which you should choose, then click on "Y1". (or whatever YN is relevant)​
The main screen should show:​
DrawInv Y1
Press "ENTER".​

This will give the graph of X = Y3.
It may also show the graph of Y = X3, depending upon whether or not Y1=X^3 is activated in the list of functions to be graphed.
