Example
Draw the graph shown below and calculate the root for Y1.
Y1 =
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

Function Analysis
# When analyzing a single graph, results appear
as soon as you select an analysis function in
step 2, so step 3 is not necessary.
# Root, local maximum value, local minimum
value, and
y
-intercept can be calculated for
rectangular coordinate graphs and inequality
graphs only.
# The
y
-intercept is the point where the graph
crosses the
y
-axis.
