Answer:
Average rate of change = 1
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is defined by,
Average rate of change =
We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4
Therefore, average rate of change of the function =
From the graph attached,
f(4) = 4
f(2) = 2
Average rate of change =
= 1
Therefore, average rate of change of the function in the given interval is 1.
