Question

what are the domain and range of this relation?
(10, 3)
(2, -3)
(9, -10)
(-2, 1)

domain: {-2, 3, 9, 10}
range: {-10, -2, 1, 3}

domain: {-2, 2, 9, 10}
range: {-10, -2, 1, 3}

domain: {-2, 2, 9, 10}
range: {-10, -3, 1, 3}

domain: {-2, 3, 9, 10}
range: {-10, -3, 1, 3}

Explanation:

Step1: Identify domain values

The domain is the set of all x-values from the ordered pairs: $\{10, 2, 9, -2\}$, sorted as $\{-2, 2, 9, 10\}$

Step2: Identify range values

The range is the set of all y-values from the ordered pairs: $\{3, -3, -10, 1\}$, sorted as $\{-10, -3, 1, 3\}$

Answer:

domain: $\{-2, 2, 9, 10\}$
range: $\{-10, -3, 1, 3\}$
