What is the value of x for which the function f(x) = 5/3x-2 becomes meaningless ?
5

3/2
2/3
If A, B and C are non empty sets then Ax (B ∪ C)=
(AxB) ∩ (AxC)
(AxC) ∩ (AxA)
(AxB) ∪ (BxC)
(AxB) ∪ (AxC)
If A = {1,2,3,4} and B= {5,6,7}, then number of relations from A to B is equal to
24

Domain of the relation {(-3,1) (-1,1) (1,0) (3,0)} is
{-3,-1,-1,3}
{-3,-1,1,3}
{1,1,0}
{1,0}
Let A= {1,2,3} and R= {(1,2), (2,2), (3,1), (3,2)}. Then the domain of R-1 is
{1,2,3}
{2,1}
{1,3}
{2,3}
If R is a relation from {11,12,13} to { 8,10,12} and is defined by y= x-3, then find the value of R-1.
{ (11,8), (10,13)}
{ (8,11), (10,13)}
{ (11,10), (8,13)}
{ (8,10), (11,13)}
Cartesian product of two sets A and B is Ax B =
{(a,b); a ∈ Aand b ∈ B}
{x; x∈A and B}
{(a,b); a∈B and b∈A}
None of these
The relation R defined on Set
{(-2,2), (-1,1), (0,0), (1,1), (2,2) }
{(-2,-2), (-2,2), (-1,1), (-1,-1), (0,0), (1,-2), (1,2), (2,-1), (2,-2)}
{(0,0), (1,2), (2,2)}
If A = {5,6,7} and B= {1,2,3,4} , then number of elements in set AxBxB is equal to

Let f: A→ B. If two or more than two elements have the same image in B, then f is said to be
