Which of the following are reflexive relations on set `A={1,2,3}`.
`R_(1)={(1,1),(2,3),(3,3),(1,3),(2,1)},R_(2)={(1,1),(3,3),(2,1),(3,2)}`

Text Solution

Verified by Experts

`R_(1)` is a reflexive relation on set A.
`R_(2)` is not a reflexive relation on A because `2epsilonA` but `(2,2)!inR_(2)`.
