The plot redraws to display a larger portion of the plot, centered about the
point you selected in the previous step.
Graphing Functions
You can graph functions by typing them in Data&Statistics, or you can graph
functions defined in other applications.
Graphing Functions Using the Plot Function Tool
You can use the Plot Function tool to plot functions in a work area that already
includes a plot on the axes. Plot Function lets you specify and graph a function
for comparison to an existing plot.
To use the Plot Function tool:
1. Create or open a problem that includes variables (from
Lists&Spreadsheet) that are plotted on a Data&Statistics work area.
Ensure that your work area contains both a horizontal axis and a vertical
axis scale.
2. From the Analyze menu, click Plot Function.
A function entry field displays in the work area.
Note: You can edit the function’s expression typed in the entry field.
However, the function graphed in Data&Statistics cannot be manipulated
or moved around the work area. To do that, use Graphs&Geometry.
3. Type the function in the entry field, and press Enter.
Note: You can rename the function by typing over f1(x): with another name,
if you choose.
