5-5 Drawing Two Graphs on the Same Screen
k k k k k Copying the Graph to the Sub-screen
Description
Dual Graph lets you split the screen into two parts. Then you can graph two different
functions in each for comparison, or draw a normal size graph on one side and its enlarged
version on the other side. This makes Dual Graph a powerful graph analysis tool.
With Dual Graph, the left side of the screen is called the “main screen,” while the right side is
called the “sub-screen.”

The graph in the main screen is actually drawn from a function.
