Solutions

Chapter 2.6, Problem 55E
To determine

To Express : The Function F(x)=1x2+1 in the form fgh .

Expert Solution

Answer to Problem 55E

The Final Answer is h(x)=x2 , g(x)=x+1 and f(x)=1x .

Explanation of Solution

Given information : The function F(x)=1x2+1 is given.

Formula used : The concept of Combining Functions is used.

Calculation :

Since, the formula of F(x) says to add 1 to x2 and then divide 1 by it, we let

  h(x)=x2 , g(x)=x+1 and f(x)=1x .

Thus,

  fgh(x)=f(g(h(x)))f(g(x2))f(x2+1)1x2+1= F(x)

Hence, the functions h, g, f, are h(x)=x2 , g(x)=x+1 and f(x)=1x .
