@iTrace function
This function lets you move a pointer around a graph and display the x- and y-
coordinates of the current pointer location. You enlarge or reduce the x- and y-
coordinates. You can display the coordinates using either seven digits or elaven
digits {including negative sign).
eUsing the trace function
To use the Trace function In combination with the Zoom func-
tion to analyze the graph for y=x?—3. Use the following range
parameters for the original graph.
Xmin : -4 Ymin : +8
Xmax: 4 Ymax: 8
Xscl 2 2 Ysel : 4
After specifying the range parameters, graph y=x?—3.
Activate the Trace function.
