Relations Test ...

Let $$R_1$$ be a relation defined by 
$$R_1 =$${ $$(a, b)| a >b , a, b \epsilon R$$}. Then $$R_1$$ is

If a relation { R } on the set { 1,2,3 } be definedby R = { ( 1,2 ) } then { R } is

The relation R defined in N as $$aRb \Leftrightarrow b$$ is divisible by a is

If $$(x^{2}-2)+(y+3)i=7+4i$$  then x and y are 

Let $$R = \left \{(2, 3), (3, 3), (2, 2), (5, 5), (2, 4), (4, 4), (4, 3)\right \}$$ be a relation on the set $$\left \{2, 3, 4, 5\right \}$$, then

If  $$g(f(x))= |sinx|$$  and  $$g(f(x))= sin^2 \sqrt{x},$$  then

If $$A = \left \{1, 2, 3, 4, 5\right \}$$ then

If $$A=\left\{1,2,4  \right\}$$, $$B=\left\{1,4,6,9  \right\}$$ and $$R$$ is a relation from $$A$$ to $$B$$ defined by $$x$$ is greater than $$y$$. The rangle of $$R$$ is :

If $$A=\{ 1,2,3\} $$ then the number of equivalance relation containing the element {1,2} is :

Let S be the set of all straight lines in a plane. Let R be a relation on S defined by $$a$$ R $$b\Leftrightarrow a||b$$. Then, R is?
