2. Click the graph you want to search for the point of interest, then click a second
time to indicate where to start the search for the point.
The second click marks the lower bound of the search region and a dotted line is

4. Press at the point to start the search. The tool shades the range.
If the search region you specified includes the point of interest, a label for the point
is displayed. If you change a graph that has points of interest identified, be sure to
check for changes in points of interest. For example, if you edit the function on the
entry line or manipulate a plot, the point where the graph intersects zero can
change.
The labelled points of interest remain visible on the graph. You can exit the tool by

Working with Variables in the Scratchpad

Scratchpad variables are shared between Scratchpad Calculate and Scratchpad Graph,
but not with any TI-Nspire™ documents. If you use the same name for a Scratchpad
variable and a variable in a document, no conflict occurs unless you attempt to copy
expressions between documents and the Scratchpad.
