Find the average rate of change of f ( x ) =   30   − x − x 2 over [1, 4].

To determine

To calculate: The average rate of change of f(x)=30xx2 over [1,4].

Explanation

Given Information:

The function is f(x)=30xx2 over [1,4].

Formula used:

The average rate of change of a function y=f(x) from x=a to x=b is defined by

Average rate of change=f(b)f(a)ba

Calculation:

Consider the provided function,

f(x)=30xx2

For x=1, substitute 1 for x in the above function,

f(x)=30xx2f(1)=301(1)2=291=28

For x=4, substitute 4 for x in the given function,
