Answer:
The average rate of change of rainfall in the rainforest between 2nd year and 6th year = <u>3 inches</u>
Step-by-step explanation:
Given function representing inches of rainfall:
![f(x)=3(x-2)+4](https://tex.z-dn.net/?f=f%28x%29%3D3%28x-2%29%2B4)
To find the average rate of change between the 2nd year and the 6th year.
Solution:
The average rate of change between interval
is given as :
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
For the given function we need to find the average rate of change between 2nd year and 6th year. ![[2,6]](https://tex.z-dn.net/?f=%5B2%2C6%5D)
So, we have:
![f(2)=3(2-2)+4=3(0)+4=4](https://tex.z-dn.net/?f=f%282%29%3D3%282-2%29%2B4%3D3%280%29%2B4%3D4)
![f(6)=3(6-2)+4=3(4)+4=12+4=16](https://tex.z-dn.net/?f=f%286%29%3D3%286-2%29%2B4%3D3%284%29%2B4%3D12%2B4%3D16)
Thus, average rate of change will be:
![\frac{f(6)-f(2)}{6-2}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%286%29-f%282%29%7D%7B6-2%7D)
⇒ ![\frac{16-4}{6-2}](https://tex.z-dn.net/?f=%5Cfrac%7B16-4%7D%7B6-2%7D)
⇒ ![\frac{12}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B4%7D)
⇒ ![3](https://tex.z-dn.net/?f=3)
Thus, the average rate of change of rainfall in the rainforest between 2nd year and 6th year = 3 inches
