None of these
Let A = {1,2,3} ,B = {a,b,c,d} be two sets and let R = {(1,a),(1,c),(2,d),(2,c)} be a relation from A to B.The domain of R is
{a,b,c,d}
{1,2}
{1,2,3}
If A B,then A × A =
B × B
(A × B) (B × A)
(A × A) (B × B)
Let A = {1,2,3},B = {a,b,c,d} be two sets and let R = {(1,a),(1,c),(2,d),(2,c)} be a relation from A to B. The range of R is
{a,c,d}
If ,then the values of x and y are
1,2
2,1
-1,-2
-2,1
