Take the cube root of both sides of the equation.Homework Statement::I just need help figuring out how to graph an equation on my calculator.

The hard part is getting y cubed

Homework Equations::Y^3=x

What goes here?

Alternative to @Mark44 's fine suggestion:Take the cube root of both sides of the equation.

You could use the "DrawInv" function.

To do this, suppose you have Y

Go to the main screen.

To graph the in verse of Y

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 "Y_{1}". (or whatever Y_{N} is relevant)

The main screen should show:

DrawInv Y_{1}

Press "ENTER".

This will give the graph of X = Y

It may also show the graph of Y = X

Alternative to @Mark44 's fine suggestion:

You could use the "DrawInv" function.

To do this, suppose you have Y_{1}=X^3 as a function to be graphed.

Go to the main screen.

To graph the in verse of Y_{1}, you will need to have your display screen show: "DrawInv Y_{1}".

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 "Y_{1}". (or whatever Y_{N}is relevant)The main screen should show:DrawInv Y_{1}Press "ENTER".

This will give the graph of X = Y^{3}.

It may also show the graph of Y = X^{3}, depending upon whether or not Y_{1}=X^3 is activated in the list of functions to be graphed.

Thank you so much! This worked! Mind if i pm you?
