<span>Evaluate when a = 8 and b = 4.
ab^2
a−b
ab² = (8)(4)² = 8*16= 128
a - b = 8 - 4 = 4 </span>
Answer:
Average rate of change = 
Step-by-step explanation:
Average rate of change of a function 'f' in the interval a ≤ x ≤ b is given by,
Average rate of change = 
We have to find the average rate of change in the interval 20 ≤ x ≤ 65
From the table attached,
f(65) = 32
f(20) = 14
Average rate of change = 
= 
= 
Therefore, average rate of change in the given interval is
.
