The Domain and Range of a Set of Ordered Pairs

Answer:

Domain:
x \in \{ 1, 3, 5, 8 \}

Range:
y \in \{ 2, 4, 6, 9 \}

Explanation:

We are given the set of ordered pairs:
R. The Domain is just the set containing all the
x values of each ordered pair of
R. Recall that in the ordered pair
(a,b),
a is the
x value. In set
R, we can see that the
x values are
\{ 1, 3, 5, 8 \}.

For the Range, it is just the set containing all the
y values of each ordered pair of
R. Recall that in the ordered pair
(a,b),
b is the
y value. In set
R, we can see that the
y values are
\{ 2, 4, 6, 9 \}.
