Solutions

Chapter 1.3, Problem 38E
To determine

To find:the given function fgh .

Expert Solution

Answer to Problem 38E

  (fgh)(x)=2x24x+1 .

Explanation of Solution

Given:

The given function is f(x)=2x1,g(x)=x2,h(x)=1x .

Calculation:

As the given function is f(x)=2x1,g(x)=x2,h(x)=1x .

  (fgh)(x)=f(g(h(x)))=f(1x)2{as g(x)=x2}=2(1x)21{as f(x)=2x1}=2(12x+x2)1=2x24x+1

Hence,the range and domain are (fgh)(x)=2x24x+1
