The tracer does not extend beyond the current Plot view
window. The table below contains brief descriptions of each
option.
Trace option Description
Off Turns tracing off so that you can move
the cursor freely in Plot view
Inside Constrains the tracer to move within a
region where the current relation is true.
You can move in any direction within
the region. Use this option for
inequalities, for example.
Edge Constrains the tracer to move along an
edge of the current relation, if one can
be found. Use this option for functions
as well as for inequalities, etc.

Selection Opens a menu so you can select which
relation to trace. This option is needed
because

from relation to relation for tracing. All
four cursor keys are needed for moving
the tracer in the Advanced Graphing
app.
