Question

14. Which of the following relations has an inverse that is not a function?

(1,1),(1,2).(3,4)
(1,2).(1,3),(4,3)
(1,4),(4,5),(5,6)
(0,0),(1,1),(2, 2)

Answer 1

The answer is the second option :)

Answer 2

(1,2).(1,3),(4,3)

Explanation:

The inverse of (1,2).(1,3),(4,3) is (2, 1), (3, 1), (3, 4) and this is not a function as a function is a set X to a set Y, not multiple to one.
