The average rate of change for this function for the interval from x = 1
to x = 3 will be 8. Therefore option B is correct.
<h3>How to find the average rate of change of something?</h3>
Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
where when
The average rate of change can be calculated as;
From x=1 to x=3,
y = 2 and y = 18
Therefore, based on the table, when:
Then:
Therefore option B is correct.
