WebDec 1, 2024 · In (b), the relation is T = { ( x, y) ∈ R 2: x = ± y }. It is reflexive because x = x for all x ∈ R. If x = ± y then y = ± x, whence it is symmetric. Also, if x = ± y and y = ± z then x = ± … WebAdvanced Math questions and answers. Hi I have a discrete math question. question 3) Consider the relation R on R defined by xRy when xy ≥ 0. Is the relation: (1) reflexive, antireflexive, or neither? (2) symmetric, antisymmetric, or neither? (3) transitive?
Web4 / 9 Proof: Consider an arbitrary binary relation R over a set A that is reflexive and cyclic. We will prove that R is an equivalence relation. To do so, we will show that R is reflexive, symmetric, and transitive. First, we’ll prove that R is reflexive. Next, we’ll prove that R is symmetric. Finally, we’ll prove that R is transitive. Notice that in this case, we had to … WebApr 7, 2024 · Solution For Question .76 The relation R={(a,b):gcd(a,b)=1,2a =b,a,b∈Z} is: A) transitive but not reflexive B Symmetric but not transitive C reflexive but not symmetric D) neither symmetric nor transi
