Answer:
Function g(x)
Explanation:
Given
See attachment for functions
Required
Which has an average rate of 3 over [1,3]
The average rate of change (m) is calculated as:

Where:
![[a,b] = [1,3]](https://img.qammunity.org/2022/formulas/mathematics/college/kntm1qxd8oy003zv2mihskln1utibfa3qj.png)
So, we have:


From the table f(x), we have:

So:



From the graph of g(x), we have:

So:




Since only one of the function has an average rate of change of 3 over the given interval,
Then g(x) answers the question
