3. Press 3 or 4 to move the dotted line to the lower bound of the search
region.
Note: You can also type a number to use as the lower bound for the
search region and press
·.
4. Press
· to mark the lower bound for the search region. The tool
shades the range.
5. Repeat steps 3 and 4 to set the upper bound of the search region.
If the search region you specified includes the point of interest, a
label for the point displays. If you change a graph that has points of
interest identified, 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 the y axis can change.
You can exit the tool by pressing
d or choosing another tool. The
labeled points of interest remain visible on the graph.
Specifying a function with domain restrictions
You can use the entry line or the Calculator application to specify a
function with domain restrictions. For multiple domain restrictions on a
function, use the piecewise function, piecewise().
In the following example, a function with a domain that is less than 2
and greater than -2 is specified on the entry line:
1. Press
/G to display the entry line.
2. Type piecewise(3, x > -2 and x < 2) on the entry line.
3. Press
· to graph the function.
