Answer:

Step-by-step explanation:
Given

Required
The average rate over ![[2,b]](https://tex.z-dn.net/?f=%5B2%2Cb%5D)
Average rate (m) is calculated using:

Where
![[a,b] = [2,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D%20%3D%20%5B2%2Cb%5D)
So, we have:

Calculate f(b) and f(2)



So, we have:



Expand the numerator

Factorize

Factor out 3b + 6

Cancel out b - 2
