AI Thread Summary
To graph the inverse of a function on a TI-84 Plus CE, start by taking the cube root of both sides of the equation, transforming Y^3 = X into Y = X^(1/3). Use the "DrawInv" function by entering "DrawInv Y1" on the main screen, where Y1 represents the function you want to invert. Access this function through the "DRAW" menu (2nd - PRGM) and select item 8, then choose the appropriate Y-VARS option. After confirming your selection, pressing "ENTER" will display the graph of the inverse function. This method effectively allows users to visualize the inverse relationship of the original equation.

Homework Statement
I just need help figuring out how to graph an equation on my calculator.

The hard part is getting y cubed
Relevant Equations
Y^3=x
What goes here?

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.
