Solutions

Chapter 2.6, Problem 57E
To determine

To Express : The Function G(x) = (4+x3)9 in the form fgh .

Expert Solution

Answer to Problem 57E

The Final Answer is h(x)=x3 , g(x)=4+x and f(x)=x9 .

Explanation of Solution

Given information : The function G(x) = (4+x3)9 is given.

Formula used : The concept of Combining Functions is used.

Calculation :

Since, the formula of G(x) says to add 4 to x3 and then take 9th power of it, we let,

  h(x)=x3 , g(x)=4+x and f(x)=x9 .

Thus,

  fgh(x)=f(g(h(x)))f(g(x3))f(4+x3) (4+ x 3 ) 9  =  G(x)

Hence, the functions h, g, f, are h(x)=x3 , g(x)=4+x and f(x)=x9 .
