Answer: Option B
Then The functions f(x) and g(x) are inverses because

Explanation:
To answer this question we must make the composition of f (x) and g (x)
We found

We know that

By definition if two functions f and g are inverses then it follows that:

So if
f and g are inverse
To find
enter the function g(x) within the function f(x) as shown below

Now

Observe that

Then The functions f(x) and g(x) are inverses because
