Which Function Is It?
Modeling From Tables
Example 2
What type of function would model this table?
Step 1. Is there a common first difference?
The y-values do not have a common first difference.
Step 2. Is there a common second difference?
The y-values do not have a common second difference.
Step 3. Is there a common ratio?
The y-values have a common ratio of 3.
Therefore, the table can be modeled by an exponential function.
