Question

The domain of the following relation: R: {(6, −2), (1, 2), (−3, −4), (−3, 2)} is

Answer 1

the definition says that the domain of a relation is
\[\left\{ a \in A:(\exists b \in B)(aRb) \right\}\]

Answer 2

so the domoain is composed by the first components of the ordered pairs.

Answer 3

and the The range of the following relation: R: {(3, −5), (1, 2), (−1, −4), (−1, 2)}

Answer 4

the range is similar to the domain:
\[\left\{ b \in B:(\exists a \in A)(aRb) \right\}\]
that is, the second components of the ordered pairs

Answer 5

The range of a relation is

the output (y) values of the relation

the input (x) values of the relation

a set of points that pair input values with output values

x and y values written in the form (x, y)

Answer 6

The domain is D={-3,1,6}
and the Range is R={-4,-2,2}
