Question

what are the domain and range of this relation?
(-5, 7)
(-3, -7)
(-10, 3)
(10, -7)

domain: {-10, -5, -3, 10}
range: {-7, 3, 7}

domain: {-10, -5, 3, 10}
range: {-7, 3, 7}

domain: {-10, -5, 3, 10}
range: {-7, 0, 3, 7}

domain: {-10, -5, -3, 10}
range: {-7, 0, 3, 7}

Explanation:

Step1: Identify domain values

The domain is the set of all x-values from the ordered pairs: $-5, -3, -10, 10$. When sorted, this is $\{-10, -5, -3, 10\}$.

Step2: Identify range values

The range is the set of all unique y-values from the ordered pairs: $7, -7, 3, -7$. The unique values sorted are $\{-7, 3, 7\}$.

Answer:

domain: $\{-10, -5, -3, 10\}$
range: $\{-7, 3, 7\}$
