Question:

Letbe a function defined as. The inverse of is map g: Range

(A)  

(B) 

(C)  

(D)

Answer:

It is given that is defined as 

Let y be an arbitrary element of Range f.

Then, there exists x ∈such that y = f(x)

Let us define g: Rangeas 

      Now,

 

 

Thus, g is the inverse of f i.e., f - 1 = g.

Hence, the inverse of f is the map g: Range, which is given by

.

The correct answer is B.
