Question 1 of 42

Answer 1

The option A is showing the domain ans the range of the function F(x) as inverse of F(x).

What is inverse function?

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by ${\displaystyle f^{-1}.}$

Here in the graph we can see that the option A has the clear range of the function.

$2------- > 1\\4------- > 2\\6------- > 3\\8------- > 4$

Hence the option A is showing the domain ans the range of the function F(x) as inverse of F(x).
