Question

Identify the set of numbers that makes up the domain in the relation {(-2, -2), (0, 2), (2, 4), (3, -6)}.

-6, -2, 2, 4
-6, -2, 0, 2, 3, 4
-2, 0, 3, 4
-2, 0, 2, 3

Answer 1

Answer:

Suppose you have two sets A and B

A={1,2,3} and B={2,3,4}

Now , A×B= {(1,2),(1,3),(1,4),(2,2),(2,3),(2,4),(3,2),(3,3),(3,4)}

Let us define a Relation,

R={(x,y): x=y, x belongs to A & y belongs to B}

R= {(2,2),(3,3)}

Domain = The set of all the first elements of the ordered pairs of Relation R = {2,3}
