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.
