given the function h(x) = 3(2)x, section a is from x = 1 to x = 2 and section b is from x = 3 to x = 4.

part a: find the average rate of change of each section.

part b: how many times greater is the average rate of change of section b than section a? explain why one rate of change is greater than the other.

PART A

The given equation is 

When , 
When , 
When , 
When , 

Between  and  there is an increase by 12
Between  and  there is an increase by 24

PART B

The change in section B is twice the change in section A. This change is an exponential change indicated by the expression  in the function. If we continue to check the rate of change between  and , we will discover that the change will be four times the rate of change between  and .
