Example 2. The set {(x, y): x = y, x,} E N} means that x has such a relation that x = y, then how do such sets Can display

The number of relations that can be defined on the set {x,y,z} is:

If p= {(x,y) in A X A:x=sqrty} be a relation on a set A={x in N :2lexle16} then the domain of p is

Let A={(x, y): x, y in z , x^(2)+y^(2) <= 16 }. Then the number of reflexive relations on set A is

Let N be the set of natural numbers and the relation R be defined on N such that R = {(x , y) : y = 2x , x , y in N} .What is the domain, codomain and range of R? Is this relation a function?

Let N be the set of natural numbers and the relation R be defined on N such that R={(x,y): y=2x,x,y in N }. what is the domain codomain and range of R ? Is this relation a functions ?

Let N be the set of natural numbers and the relation R be defined on N such that R = {(x, y) : y = 2x, x, y in N} . Is this relation a function ?

If a set A has a relation R and (x, y) in R implies (y, x) R AA x,y in A then the relation R is called

In some question of sets, we have to make the use of graphs For example A={(x,y):y=e^(x), x in R} B={{x,y}: y=-x. x in R} Find n(A cap B) It is clear that y=e^(x) and y=-x intersect at one pont. Hence n(A cap B)=1 A:{(x,y):y=sqrt(4-x^(2)), x in [-2,2]} B={(x,y):y=|x|, x in R} Then n(A cap B)
