#### Solution Preview

1. R is reflexive since it contains (1,1),(2,2) and (3,3)

2. R is not symmetric. It contains (3,1) but not (1,3)

3. R is antisymmetric. We need to check that if (x,y) and (y,x) are in R then x=y. The only pairs (x,y) in R such ...

#### Solution Summary

It is determined if a relation is reflexive, symmetric, antisymmetric, transitive, partial order and its equivalence.
