V. DRAW Menu

B. DRAW Inverse

This menu option will draw the inverse of a graph but does not give the definition of the inverse. TABLE, TRACE, etc will not be accessible for the inverse drawn. It is a drawing only. If the function is not 1:1 then the inverse is not a function.

Example: Draw the inverse of the function shown below.

Enter the function.
Set a window to fit the function.
Graph the function.
Access the DRAW menu and select item 8.
This will appear on the home screen.
Go to the VARS button.
Select Y-VARS.
Select Function.
Select item 1 and this screen will appear.
Press enter and the inverse graph will be drawn.

To delete the inverse, enter 1.
