Which pair of functions is not a pair of inverse fuctions

The pair of functions that is not inverse functions are:

Step-by-step explanation:

We know that two functions a and b are said to be inverse of each other if:

             f(g(x))=g(f(x))=x

i.e. the compositions of the function gives identity.

and the inverse of the given function is calculated by equation the function to y and then calculating the value of x in terms of y.

and the function in terms of y is the inverse function.

A)

Now if f(x)=y then

B)

i.e.

C)

i.e. we have:

D)

if f(x)=y then

             Hence, option: D is the answer.
