for the selected sequence mode. Specify the parameters required
for the plot type. You can use the Attributes tool to change
between the Time plot and Web plot of a sequence.

to graph the relation.
When you press

to graph the expression, Graphs & Geometry
hides the entry line and shows an uncluttered view of the graph.
3. Take one of the following actions to continue your work:
– To graph the one relation and then immediately specify another,

– To graph the relation and activate the Entry Line Expansion
button , press

.
After you graph f1( x ) and redisplay the entry line, the entry line
displays f2 (x)= to enable you to enter another function. If you
select or trace a function, that function displays on the entry line.
As you graph multiple relations on the graph axes,
Graphs & Geometry labels each, unless the Graphs & Geometry
setting "Automatically hide plot labels" is checked.. You can
define and graph a maximum of 99 of each type. For example, you
use function mode to specify functions (
f1(x) - f99(x) ). You can
rename relations using custom names, for example, g1(x) .
Note: The entry line is automatically hidden when you are not
entering or editing relations. To display it at any time, press
