(Section 20)
In mathematics it is important to view
functions numerically, graphically, and analytically. Prior to the
graphing calculator most mathematics courses concentrated on the
analytical view of functions only. With the TI-83 and TI-89 graphing
calculators it is possible to view functions numerically and graphically.
Most students are familiar with graphing equations on a calculator, but
the calculator can be used to understand functions in other ways too.
You will be asked to refer to the above quadratic data, equation, and
tables in section 18. |
