If point (a,b) lies on the graph of function f, which of the following points must lie on the graph of the inverse f?

A

(a,b)

B

(-a,b)

C

(a,-b)

D

(b,a)

Text Solution

Verified by Experts

The correct Answer is:
D
Since inverse sunctions are symmetric about the line y=x , if point (A,b) lies on f, point (b,a) must lie on `f^(-1)` [1]
