Drawing a Function or Inverse on a Graph
For comparison purposes, you may want to draw a function over your current graph.
Typically, the drawn function is some variation of the graph. You can also draw the
inverse of a function. (These operations are not available for 3D graphs.)

Execute
DrawFunc, DrawParm, or DrawPol from the Home screen or a program. You
cannot draw a function or equation interactively from the Graph screen.

For example:
1. Define
y1(x)=.1x
3
–2x+6 on the Y= Editor,
and graph the function.
