Example Graph the two functions shown below and then determine the y -
coordinate for x = 0.5 and the x -coordinate for y = 2.2 on graph Y2.
Y1 = x + 1, Y2 = x ( x + 2)( x – 2)
Use the following V-Window settings.
Xmin = –6.3, Xmax = 6.3, Xscale = 1
Ymin = –3.1, Ymax = 3.1, Yscale = 1 (initial defaults)

Function Analysis
# When there are multiple results for the above
procedure, press e to calculate the next
value. Pressing d returns to the previous
value.
# Step 3 of the above procedure is skipped
when there is only one graph on the display.
# The X-CAL value cannot be obtained for a
parametric function graph.
# After obtaining coordinates with the above
procedure, you can input different coordinates
by first pressing v.
