Chapter 4 Graphing

Example To graph the inequality y > x

– 2x – 6

Use the following View Window parameters.

Xmin = –6 Ymin = –10

Xmax = 6 Ymax = 10

Xscl = 1 Yscl = 5

1. In the set-up screen, specify the appropriate graph type for F-Type.

!Z[1(Y>)Q

2. Input the inequality.

A!4(SKTCH)1(Cls)w

2(GRPH)[1(Y>)

Tx-cT-g

3. Press w to draw the graph.

5. Other Graphing Functions

The functions described in this section tell you how to read the x- and y-coordinates

at a given point, and how to zoom in and zoom out on a graph.

• These functions can be used with rectangular coordinate, parametric, and in-

equality graphs only.

k Connect Type and Plot Type Graphs (D-Type)

You can use the D-Type setting of the set-up screen to specify one of two graph

types.

•Connect type (Conct)

Points are plotted and connected by lines to create a curve.

•Plot

Points are plotted without being connected.
