### Question

#### Let

- 1

### Hint:

To find the given composite function we can first find each function separately and then divide the two. To solve f(g(x)) first we need to put the value of x in g(x) then the value obtained will be used in f(x). Same way we can fnd g(f(x)).

#### The correct answer is: 1

#### For

f(g(x))=f(1+x-)

f(g(2009))= f (1+2009-)

= f (1+2009-2009)

= f (1)

=1 (as x is greater than 0)

g(f(x))=g(f(2009))

= g(1) (f(2009)=0 as x is greater than 0)

=1+1-

=2+1

=1
