k k k k k Determining Points of Intersection for Two Graphs
Specify Graph Y1.
Specify the second graph (Graph Y3, here) to determine the points of intersection.

(This puts the unit into standby waiting
for selection of a graph.)
w
• Pressing w changes " k " into "
specification of the first graph.
cw
• Use f and c to move " k " on the
second graph.
• Intersections are found starting from the left.
e
• 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).
• Note that the above operation can be performed on rectangular coordinate (Y=)
and inequality graphs only.
