Relations Rand s are defined by R = ((1,5), (2,2), (3,4), (5,2)} and s = ((2,4), (3,4), (3,1), (5,5)). Then Dom(s o R) : %3D %3D %3D 0 (2,3,5) (1,2,3) o (1,2,5) O (1,2,3,4) QUESTION 5 Let be the relation defined on the set N of.natural numbers for x.VEN by xRy if and only if x +y is divisible by 3. Then: Ris symmetric g is reflexive and symmetric O R is reflexive Ris symmetric and transitive QUESTION 6 Let A = (1,2,3) define a relation R on (A) (the Power Set of A) by XRY if and only if X and Y have the same number of elements. The the equivalence class X of X = (2,3} is X = {{2,3), {1,2), {1,3}}- %3D O True False
