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 (initial defaults)

Function Analysis
#When analyzing a single graph, results appear
as soon as you select an analysis function in
step 3, so step 4 is not necessary.
# Root, local maximum value, local minimum
value, and
y-intercept can be calculated for
rectangular coordinate graphs and inequality
graphs only.
#Graph analysis is not possible for the graph
whose function is the format X = constant.
# The
y-intercept is the point where the graph
crosses the
y-axis.
