Answer: C < B < A
<u>Step-by-step explanation:</u>
First, let's evaluate the growth rate of A from [1, 3]
![f(x) = 200\bigg(\dfrac{3}{2}\bigg)^1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20200%5Cbigg%28%5Cdfrac%7B3%7D%7B2%7D%5Cbigg%29%5E1)
= 300
coordinate is (1, 300)
![f(x) = 200\bigg(\dfrac{3}{2}\bigg)^3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20200%5Cbigg%28%5Cdfrac%7B3%7D%7B2%7D%5Cbigg%29%5E3)
= 675
coordinate is (3, 675)
Average growth rate (AGR) is: ![\dfrac{675-300}{3-1} = \dfrac{375}{2} = 187.5](https://tex.z-dn.net/?f=%5Cdfrac%7B675-300%7D%7B3-1%7D%20%3D%20%5Cdfrac%7B375%7D%7B2%7D%20%3D%20187.5)
AGR (A) = 187.5

Next, let's evaluate the growth rate of B from [1, 3]
The coordinates are already provided as (1, 120) and (3, 480)
Average growth rate (AGR) is: ![\dfrac{480-120}{3-1} = \dfrac{360}{2} = 180](https://tex.z-dn.net/?f=%5Cdfrac%7B480-120%7D%7B3-1%7D%20%3D%20%5Cdfrac%7B360%7D%7B2%7D%20%3D%20180)
AGR (B) = 180
*************************************************************************************
Lastly, let's evaluate the growth rate of C from [1, 3]
f(x) = 600(1.2)ˣ
f(x) = 600(1.2)¹
= 720
coordinate is (1, 720)
f(x) = 600(1.2)³
= 1036.8
coordinate is (3, 1036.8)
Average growth rate (AGR) is: ![\dfrac{1036.8-720}{3-1} = \dfrac{316.8}{2} = 158.4](https://tex.z-dn.net/?f=%5Cdfrac%7B1036.8-720%7D%7B3-1%7D%20%3D%20%5Cdfrac%7B316.8%7D%7B2%7D%20%3D%20158.4)
AGR (C) = 158.4
