Question

what is the domain of this relation?
(-10, 3)
(3, 2)
(0, -8)
(8, -4)
(7, 6)
{2, 3, 4, 6, 8} {-8, -4, 2, 3, 6}
{-10, 0, 3, 7, 8} {0, 3, 7, 8}

Explanation:

Step1: Identify domain definition

The domain of a relation is the set of all first values (x-values) from each ordered pair.

Step2: Extract x-values from pairs

From $(-10, 3), (3, 2), (0, -8), (8, -4), (7, 6)$, the x-values are $-10, 3, 0, 8, 7$.

Step3: Organize into ordered set

Arrange the x-values in ascending order to form the domain set: $\{-10, 0, 3, 7, 8\}$.

Step4: Match to given options

The set $\{-10, 0, 3, 7, 8\}$ matches one of the provided options.

Answer:

$\{-10, 0, 3, 7, 8\}$ (the bottom-left option)
