Solutions

Chapter 3.1, Problem 48E
To determine

To find:

The differentiation of the given function of the interval

Expert Solution

Answer to Problem 48E

The function of interval is (53,1)

Explanation of Solution

Given:

The function is

  f(x)=x34x2+5x

Concept used:

Definition of the differentiation:-Differentiation is the action of computing a derivative

The derivative of a function y=f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to x

Calculation:

The function

  f(x)=x34x2+5x...................(1)

The derivative of a function

  y=f(x)y=f(x)=dydx

Differentiating the equation (1) with respect to x

  dydx=ddx(x34x2+5x)f(x)=3x28x+5

The derivative is zero

  f(x)=03x28x+5=03x23x5x+5=03x(x1)5(x1)=0(3x5)(x1)=0x=53,1

The function of interval is (53,1)
