Let `S = {a , b , c} a n d T = {1, 2, 3}`. Find `F^(-1)`of the following functions F from S to T, if it exists.(i `) F = {(a , 3), (b , 2), (c , 1)}`(ii) `F = {(a , 2), (b , 1), (c , 1)}`

Text Solution

Verified by Experts

The correct Answer is:
`F^(-1)={(3,a),(2,b),(1,c)}` (ii) `F^(-1)` does not exist.
