Solutions

Chapter 2, Problem 56RE
To determine

Find the average rate of change of the function between the given points.

Expert Solution

Answer to Problem 56RE

The average rate of change of the function between the given points is 112

Explanation of Solution

Given information: Consider the function, f(x)=1x2, on the interval [4,8]

Calculation:

Recall the formula for average rate of change is A(x)=f(b)f(a)ba

  =f(8)f(4)84=1821424         Since f(x)=1x2=112

Thus, the average rate of change of the function between the given points is 112
