Answer:




Step-by-step explanation:
Given
See attachment for table
Solving (a): Rate of change between 2nd and 3rd point on A
The rate of change is calculated as:

In table A, the 2nd and 3rd point is:


So, the average rate of change is:



Solving (b): Rate of change between 3rd and 4th point on A
In table A, the 3rd and 4th point is:


So, the average rate of change is:



Solving (c): Rate of change between 2nd and 3rd point on B
In table B, the 2nd and 3rd point is:


So, the average rate of change is:



Solving (d): Rate of change between 4th and 5th point on B
In table B, the 4th and 5th point is:


So, the average rate of change is:
