The average rate of change of a function is its slope
The average rate of change of the function is 4
<h3>How to calculate the average rate of change</h3>
The function is given as:

The interval of the function is given as:
x = 2 to x =6
Start by calculating f(2) and f(6)


The average rate of change of the function is then calculated as:


So, we have:



Hence, the average rate of change of the function is 4
