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.
