What is the value of x for which the function f(x) = 5/3x-2 becomes meaningless ?
5
3
3/2
2/3
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)}
None of these
If A, B and C are non empty sets then Ax (B ∪ C)=
(AxB) ∩ (AxC)
(AxC) ∩ (AxA)
(AxB) ∪ (BxC)
(AxB) ∪ (AxC)
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}
Let R be a set of real numbers and let S be a relaion defined on R as follows. xSy, iff x2+y2=1.Which one of the following statements is correct?
S is a reflexive relation
S is a symmetric relation
S is a transitive relation
S is an anti-symmetric relation
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)}
If AxB = {(1,1), (1,2), (1,3),(2,1),(2,2),(2,3)}, then A is equal to
{1,2}
If (a,b) = (2,3), then (a2+1, b2+2) is equal to
(3,5)
(5,11)
(1,2)
Let f: R→R; f(x) = (x2-3x+2). Then f(f(y))=
x4+6x3+10x2-3x
x4-6x3-10x2-3x
x4-6x3+10x2-3x
x4+6x3-10x2+3x
If A = {2,3} and B = {1,2} then BxA is equal to
{(2,1), (2,2), (3,1) (3,2)}
{(1,2), (1,3), (2,2), (2,3)}
{(2,1), (3,2)}
{(1,2), (2,3)}
