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.
