In 1-8, a number of relations are defined on the et A={0,1,2,3}. For each relation:

1. Drae the directed graph.
2. Determine whethrer the relation is reflexive.
3. Determine whether the relation is symmetric.
4. Determine whether the realtion is transitive.

Give a counter example in each case in which the relation does not satisfy one of the properties.

R 4 = { ( 1 , 2 ) , ( 2 , 1 ) , ( 1 , 3 ) , ( 3 , 1 ) }
