4. To see the ZSquare window variables, press p and notice the new values for Xmin, Xmax, Ymin, and Ymax. Defining Graphs TI-84 Plus-Graphing Mode Similarities Chapter 3 specifically describes function graphing, but the steps shown here are similar for each TI-84 Plus graphing mode. Chapters 4, 5, and 6 describe aspects that are unique to parametric graphing, polar graphing, and sequence graphing. Defining a Graph To define a graph in any graphing mode, follow these steps. Some steps are not always necessary. 1. Press z and set the appropriate graph mode. 2. Press o and enter, edit, or select one or more functions in the Y= editor. 3. Deselect stat plots, if necessary. 4. Set the graph style for each function. 5. Press p and define the viewing window variables. 6. Press y . and select the graph format settings. Displaying and Exploring a Graph After you have defined a graph, press s to display it. Explore the behavior of the function or functions using the TI-84 Plus tools described in this chapter. Saving a Graph for Later Use You can store the elements that define the current graph to any of 10 graph database variables (GDB1 through GDB9, and GDB0; Chapter 8). To recreate the current graph later, simply recall the graph database to which you stored the original graph. These types of information are stored in a GDB. • Y= functions • Graph style settings • Window settings • Format settings Chapter 3: Function Graphing 66
