@Overdrawing Inequality Graphs .
If
you
draw
two
or
more
inequality
function
graphs
on
the
same
screen,
the
area
contain-
ing
values
that
satisfy
both
functions
is
filled
in.
In
the
following
input
sequence
we
will
input
two
functions
with
a
single
operation:
D
Note
the
(3)
operation
that
separates
the
two
functions.
@ To overdraw inequality graphs

To

Specifying the Graph Range
When drawing inequality graphs, you-can specify the maximum and. minimum values to
be applied. Use the following format:
[Fn] (inequality) (2) G4 (1) Xmin G) Xmax aC)
(n=1 to 4)
To graph y<2x—5 using the range 0<x<2, and the following range
parameters:

To draw integration graphs, you press Gia), enter the function, and then press 3. The
unit produces the graph on the display with the solution range filled in.
*Whenever drawing a new integration graph, you should always

*Do not try to use the BASE, EQUA, GRAPH, DYNA or TABLE Mode for integation
graphing.
