Analyzing a Function Graph

k k k k k Determining Points of Intersection for Two Graphs

Example

Specify Graph A.

• Pressing w changes " k " into "

fication of the first graph.

Specify the second graph (Graph C, here) to determine the points of intersection.

• Use f and c to move " k " on the second

graph.

• Intersections are found starting from the left.

• The next intersection to the right is found. If

there is no intersection to the right, nothing

happens when you perform this operation.

• You can use d to move back to the left.

• If there are only two graphs, pressing 5 (ISCT) directly displays the intersec-

tions (selection of the graph is not required).

To draw the following three graphs and then determine the points

of intersection for the Graph A and Graph C.
