This graph indicates that recursion formula a
n +1
= –3 a
n
2 + 3 a
n
is convergent.
Example 2 To determine whether or not the recursion formula b
n +1
=
3 b
n
+ 0.2 is convergent or divergent.
Use the following table range.
Start = 0 End = 6
b
0
= 0.02 b
n
Str = 0.02
Use the View Window parameters from Example 1.
1. Press 6 (TABL) 4 (WEB) to draw the graph.

2. Press w and then either
f
or
c
to make the pointer appear at the pointer
start point ( b
n
Str = 0.02).
w
c
(or
f
)
• The Y value for the pointer start point is always 0.
