The Function aplet enables you to explore up to 10
real–valued, rectangular functions y in terms of x. For

.
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.
The following example involves two functions: a linear
function
y
=
1 x
and a quadratic equation
