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 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.
