Solutions

Chapter 3.1, Problem 37E
To determine

To Find: The maximum or minimum value of the function f(s)=s21.2s+16

Expert Solution

Answer to Problem 37E

The value of minima is f(610)=1564100

Explanation of Solution

Given: The function is f(s)=s21.2s+16

Calculation:

This is a quadratic function with a=1, and b=1.2 . Thus, the maximum or minimum value occurs at

  x=b2a=1.22(1)=1.22=610

Since, a>0 , the function has the minimum value

  f(610)=(610)21.2(610)+16=1564100
