8-6 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, polar coordinate, para-

metric, X = constant, and inequality graphs only.

k Connect Type and Plot Type Graphs (Draw Type)

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

types.

• Connect

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

• Plot

Points are plotted without being connected.

k Trace

With trace, you can move a flashing pointer along a graph with the f, c, d, and

e cursor keys and obtain readouts of coordinates at each point. The following

shows the different types of coordinate readouts produced by trace.

• Rectangular Coordinate Graph • Polar Coordinate Graph

• Parametric Function Graph • X = Constant Graph

• Inequality Graph

uTo use trace to read coordinates

Example To determine the points of intersection for graphs produced by

the following functions:

Y1 = x

– 3

Y2 = –x + 2

Use the following View Window parameters.

Xmin = –5 Ymin = –10

Xmax = 5 Ymax = 10

Xscale = 1 Yscale = 2
