Option (2)

Step-by-step explanation:

If m(x) and n(x) are the functions inverse of each other,

Then the following condition should be fulfilled,

m[n(x)] = n[m(x)] = x

Here, m(x) = and n(x) =

m[n(x)] =

          =

          = x

n[m(x)] =

           =

           = x

Therefore, will be the correct option.

Option (2) will be the answer.
