aRb if a-b>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

aRb iff 1+ab>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

aRb if |a|<=b is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

a R b if |a|lt=b is defined on the set of real numbers, find whether it is reflexive, symmetric or transitive.

The following relation is defined on the set of real number: a R biff1+a b >0 Find whether this relation is reflexive, symmetric or transitive.

Check whether the relation-R defined in the set of all real numbers as R={(a,b): a le b^(3)} is reflexive, symmetric or transitive.

Let R be a relation defined on the set of real numbers by aRb hArr1+ab>0 then R is (A) Reflexive and symmetric (B) Transitive (C) Anti symmetric (D) Equivalence

Check whether the relationR in the set R of real numbers defined by : R={(a,b):1+abgt0} is reflexive, symmetric or transitive.

R_(3)={(b,c)} is defined on set A={a,b,c}. Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.
