A) \[\{(a,1),(a,3)\}\]
B) \[\{(b,1),(c,2),(d,1)\}\]
C) \[\{(a,2),(b,3),(3,b)\}\]
D) \[\{(a,1),(b,2),(c,3)\}\]
Correct Answer: C
Solution :
[c] \[\{(a,1),(a,3)\}\subseteq A\times B\therefore \] This is a relation. \[\{(b,1),(c,2),(d,1)\}\subseteq A\times B\therefore \] This is a relation. \[(3,b)\notin A\times B\] \[\therefore \{(a,2),(b,3),(3,b)\}\] is not a relation from A to B, \[(a,1)(b,2)(c,3)\] is a relation from A to B.You need to login to perform this action.
