Answer

0 --> 0 0 --> 1 1 --> 1 1 --> 2 2 --> 2 2 --> 3 1. Not Reflexive 2. Not Symmetric 3. Transitive

Work Step by Step

Counterexample for reflexive property: (3, 3) is not included in R2, so the relation is not reflexive. Counterexample for symmetric property: (1, 0) is not included in R2, but (0, 1) is, so the relation is not symmetric. Counterexample for transitive property: (0, 1) and (1, 2) are included in R2, but (0, 2) is not, so the relation is not transitive.
