State with reason whether following functions have inverse (i) `f:{1,2,3,4} ->{10} w i t h f={(1, 10),(2, 10),(3, 10),(4, 10)}`(ii) `g:{5, 6, 7, 8}->{1,2,3,4} w i t h g={(5, 4),(6, 3),(7, 4),(8, 2)}`(iii) `h :{2,3,4,5} ->{7,9

Text Solution

Verified by Experts

The correct Answer is:
(i) No, since f is many-one
(ii) No, since g is many-one.
(iii) Yes , since h is one-one onto.
