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.
