Determine whether the relation R on the set of all integers is reflexive, irreflexive, symmetric, antisymmetric, and/or transitive, where (x, y) is in R if and only if: A. x does not equal y symmetric antisymmetric reflexive irreflexive transitive none B. x * y > = 1 symmetric antisymmetric reflexive irreflexive transitive none C. x = y + 1 or x = y - 1 symmetric antisymmetric reflexive irreflexive transitive none D. x is a multiple of y symmetric reflexive irreflexive transitive none E. x and y are both negative or both nonnegative symmetric antisymmetric reflexive irreflexive transitive none F. x = y^2 symmetric antisymmetric reflexive irreflexive transitive none G. x > = y^2 symmetric antisymmetric reflexive irreflexive transitive none
