The Domain and Range of a Set of Ordered Pairs
Answer:
Domain: [tex]x \in \{ 1, 3, 5, 8 \}[/tex]
Range: [tex]y \in \{ 2, 4, 6, 9 \}[/tex]
Step-by-step explanation:
We are given the set of ordered pairs: [tex]R[/tex]. The Domain is just the set containing all the [tex]x[/tex] values of each ordered pair of [tex]R[/tex]. Recall that in the ordered pair [tex](a,b)[/tex], [tex]a[/tex] is the [tex]x[/tex] value. In set [tex]R[/tex], we can see that the [tex]x[/tex] values are [tex]\{ 1, 3, 5, 8 \}[/tex].
For the Range, it is just the set containing all the [tex]y[/tex] values of each ordered pair of [tex]R[/tex]. Recall that in the ordered pair [tex](a,b)[/tex], [tex]b[/tex] is the [tex]y[/tex] value. In set [tex]R[/tex], we can see that the [tex]y[/tex] values are [tex]\{ 2, 4, 6, 9 \}[/tex].
