Answer:
(g•f)(x) = x.
Step-by-step explanation:
Let 
, then the inverse function of the f(x) is 
So, (g•f)(x) = ![g[f(x)] = g(x^{2} + 1 ) = \sqrt{(x^{2} + 1) - 1} = \sqrt{x^{2} } = x](https://tex.z-dn.net/?f=g%5Bf%28x%29%5D%20%3D%20g%28x%5E%7B2%7D%20%2B%201%20%29%20%3D%20%5Csqrt%7B%28x%5E%7B2%7D%20%2B%201%29%20-%201%7D%20%3D%20%5Csqrt%7Bx%5E%7B2%7D%20%7D%20%3D%20x)
Therefore, we can write if f(x) and g(x) are inverse functions of each other, then (g•f)(x) = x.
