Question

For each pair of functions and below, find and .

Answer 1

Answer:

1- Inverses .

2 - Not inverses.  

Step-by-step explanation:

Notice that

1 -

$f(g(x))= 3/(3/x) = (3x)/3 = x$

Since their composition is the identity, then they are inverses.

2 -

$f(g(x)) = ((-x+4)+4) = -x+8$

Since their composition is not the identity, then they are not inverses.
