function
1. Open a new document and start the Notes application.
2. Define a function in a math box, evaluate, and hide the output using
the Math Box attributes.
3. Type some more text; for example: “Real Roots of f1(x) are:”
4. In a new math box, type: polyRoots(f1(x),x).
5. Press
· and hide the input of this math box by using the Math Box
attributes dialog box.
6. Use the Page Layout toolbar icon to select the split layout.
7. Add the Graph application and plot f1(x).
