Question

plz ans this quickly ...
Is the relation R in the set A={1,2,3,4,5} defined as R={ (a,b) : b =a+1} is reflexive???

Answer 1

Answer:

NO

Step-by-step explanation:

R is reflexive....

if (a,a) € R ; a€A

but (a,b) = (a,a+1) €R

and since a ≠ a+1 we never have (a,a) in R

hence R is not reflexive
