Syntax: DrawInv function

Draws the inverse of a function.

The inverse of function (function with the X and Y values switched) is drawn on the graph screen.

function can be either a function specified directly (such as 3X^2) or one of the graph functions (such as Y3)

Draws a parabola starting at (0,0) and moving off to the right:

:DrawInv X^2

-You should see a parabola starting at (0,0) moving off to the right.
+Draws the inverse of a function.
-Also you can use equations instead of strings.  The following draws the inverse of the equation in Y<sub>1</sub>:
