You can graph a function or relation directly from its context menu. This feature is available for many functions and relations on Notes, Scratchpad, and Calculator pages.

If page layout options allow, the graph appears on the same page as the function or relation. Otherwise, the graph appears on a separate Graphs page.
The type of graph created depends on:
| • | The type of function or relation. |
| • | Any restrictions imposed by an active Press‑to‑Test session. |
This example uses a Notes page to explore a quadratic function interactively.
| 1. | Insert a math box on a new Notes page, and enter the following function definition: |
Define f1(x)=x2-1·x-4
| 2. | Display the context menu of the Define statement. Windows®: Right-click the statement. Mac®: Hold “, and click the statement. Handheld: Point to the statement, and press / b. |
| 3. | Select Graph from the context menu. |
The graph appears. The graph and the math box are linked so that any adjustment to one affects the other.
| 4. | Explore the relationship between the defined function and its graph: |
| - | Drag the ends or center of the graph to manipulate it, and observe the changes to the function definition. |
—or—
| - | Edit the defined function in the math box, and observe the changes to the graph. |
