Problem 2. (10 points) Suppose that R and S are reflexive relations over a set A. Either prove, or give a counterexample to disprove, each of the following statements: a) RU S is reflexive b) RnS is reflexive c) R - S is anti-reflexive d) So R is reflexive is reexive. The relation R-1, the inverse of R, is defined as Ra, b): (b, a) E R)
