Example Graph the two functions shown below, and determine the point of
intersection between Y1 and Y2.
Y1 =
x + 1, Y2 = x

Use the following V-Window settings.
Xmin = –5, Xmax = 5, Xscale = 1
Ymin = –5, Ymax = 5, Yscale = 1

Function Analysis
# In the case of two graphs, the point of
intersection is calculated immediately after
you press !55 in step 2.
# You can calculate the point of intersection for
rectangular coordinate graphs and inequality
graphs only.
