Let R be a relation on the set of integers where a Rb a = b ( mod 5) Mark only the correct statements. Hint: There are ten correct statements. The composition of R with itself is R The inverse of R is R R is transitive For all integers a, b, c and d, if aRb and cRd then (a-c)R(b-d) (8,1) is a member of R. The equivalence class [0] = [4]. R is reflexive The union of the classes [-15],[-13].[-11],[1], and [18] is the set of integers. 1R8. The equivalence class [-2] = [3]. The complement of R is R Ris antisymmetric The union of the classes [1],[2],[3] and [4] is the set of integers. The intersection of [-2] and [3] is the empty set. R is irreflexive R is asymmetric Ris symmetric The equivalence class [-2] is a subset of the integers. The equivalence class [1] is a subset of R. R is an equivalence relation on the set of integers.
