Explain why the relation R = {(x, y) : 3x − y = 0} is not reflexive on the set A = {1, 2, 3 … 13, 14}.
Explain why the relation R = {(x, y) : 3x − y = 0} is not reflexive on the set A = {1, 2, 3 … 13, 14}.
The relation R is not reflexive because for a relation to be reflexive, it must contain all pairs (a, a) where a is an element of the set. In this case, R does not contain pairs like (1, 1), (2, 2) ... (14, 14), so it is not reflexive.
Why is the relation R = {(x, y) : 3x − y = 0} not symmetric?
Why is the relation R = {(x, y) : 3x − y = 0} not symmetric?
The relation R is not symmetric because although (1, 3) is in R, (3, 1) is not in R. For a relation to be symmetric, if (a, b) is in R, then (b, a) must also be in R, which is not the case here.
Explain why the relation R = {(x, y) : 3x − y = 0} is not transitive.
Explain why the relation R = {(x, y) : 3x − y = 0} is not transitive.
The relation R is not transitive because although (1, 3) and (3, 9) are in R, (1, 9) is not in R. For a relation to be transitive, if (a, b) and (b, c) are in R, then (a, c) must also be in R, which is not the case here.
Determine whether the relation R = {(x, y) : y = x + 5 and x < 4} on the set of natural numbers is reflexive, symmetric, and transitive.
Determine whether the relation R = {(x, y) : y = x + 5 and x < 4} on the set of natural numbers is reflexive, symmetric, and transitive.
