Answer:

(g•f)(x) = x.

Step-by-step explanation:

Let $f(x) = x^{2} + 1$ , then the inverse function of the f(x) is $g(x) = \sqrt{x - 1}$

So, (g•f)(x) = $g[f(x)] = g(x^{2} + 1 ) = \sqrt{(x^{2} + 1) - 1} = \sqrt{x^{2} } = x$

Therefore, we can write if f(x) and g(x) are inverse functions of each other, then (g•f)(x) = x.

Hence, option D is correct. (Answer)
