Editing Tables and Drawing Graphs
This graph indicates that recursion formula
Example 2
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
• The Y value for the pointer start point is always 0.
To determine whether or not the recursion formula
b
3 + 0.2 is convergent or divergent.
n
Use the following table range.
Start = 0
b
= 0.02
0
Use the View Window parameters from Example 1.
