DrawInv draws the function as if the Y and X values were switched. The following draws the inverse of y=x2:

DrawInv("X^2")

You should see a parabola starting at (0,0) moving off to the right.

Also you can use equations instead of strings. The following draws the inverse of the equation in Y1:

DrawInv(Y1)

You can access the equation variables by hitting [Vars], [Right] to Y-Vars, and finally to Functions.
