#### Solutions

Chapter 2.6, Problem 50E
To determine

## To find: The functions f(x) and g(x) such that F(x)=x+1 is equal to fog .

Expert Solution

The functions f(x) and g(x) such that F(x)=x+1 is equal to fog are x+1 and x respectively.

### Explanation of Solution

Given information:

The function is F(x)=x+1 .

Calculation:

The function F(x)=x+1 is x added to 1 .

So, take the functions f(x) equal to x+1 and g(x) equal to x .

Verify that (fog)(x)=F(x) .

(fog)(x)=f(g(x))=f(x)=x+1=F(x)

Therefore, the functions f(x) and g(x) such that F(x)=x+1 is equal to fog are x+1 and x respectively.
