About the Function aplet
The Function aplet enables you to explore up to 10
real-valued, rectangular functions y in terms of x. For
example .
Once you have defined a function you can:
• create graphs to find roots, intercepts, slope, signed
area, and extrema
• create tables to evaluate functions at particular
values.
This chapter demonstrates the basic tools of the Function
aplet by stepping you through an example. See “Aplet
views” on page 2-1 for further information about the
functionality of the Symbolic, Numeric, and Plot views.
Getting started with the Function aplet
The following example involves two functions: a linear
function and a quadratic equation
.

The Function aplet starts
in the Symbolic view.
The Symbolic view is the defining view for Function,
Parametric, Polar, and Sequence aplets. The other
views are derived from the symbolic expression.
