1. Press b

plot in Trace model.
2. (Optional) To change the trace step increment for tracing, press
b 5 3
After you type a different step increment, the Graph Trace tool moves
across the graph in steps of that size.
3. Use Graph Trace to explore a plot in the following ways:
• Move to a point and hover to move the trace cursor to that point.

• Press or
The coordinates of each point traced are displayed.

• Press or
coordinates update to reflect the new location of the trace. The
trace cursor is positioned on the point of the new graph or plot
with the closest x value to the last point identified on the
previously traced function or graph.
• Type a number and press
point on the plot with independent coordinates nearest the typed
value.
