This chapter describes the steps used to display and explore a
graph. Before using this chapter, you should be familiar with
Chapter 2.
Although this chapter describes how to graph y(x) functions, the
basic steps apply to all graphing modes. Later chapters give
specific information about the other graphing modes.
