Defining a Parametric Graph
The steps for defining a parametric graph are similar to the steps for defining a function
graph. This chapter assumes that you are familiar with Chapter 5: Function Graphing and
Chapter 6: Graph Tools. This chapter details those aspects of parametric graphing that
differ from function graphing.
