8-6 Other Graphing Functions
The functions described in this section tell you how to read the
nates at a given point, and how to zoom in and zoom out on a graph.
k k k k k Connect Type and Plot Type Graphs (Draw Type)
P.5 You can use the Draw Type setting of the set up screen to specify one of two
graph types.
k k k k k Trace
With trace, you can move a flashing pointer along a graph with the cursor keys
and obtain readouts of coordinates at each point. The following shows the different
types of coordinate readouts produced by trace.
u u u u u To use trace to read coordinates
• These functions can be used with rectangular coordinate, polar coordinate,
parametric, X = constant, and inequality graphs only.
• Connect
Points are plotted and connected by lines to create a curve.
• Plot
Points are plotted without being connected.
• Rectangular Coordinate Graph
• Parametric Function Graph
• Inequality Graph
Example To determine the points of intersection for graphs produced by
the following functions:
