Question

what are the domain and range of this relation?
(6, 8)
(-6, 1)
(-4, -5)
(-9, -6)
domain: {-9, -6, -4, 6}
range: {-6, -5, 1, 8}
domain: {-9, -4, 6}
range: {-6, -5, 8}
domain: {-9, -4, 6}
range: {-6, -5, 1, 8}
domain: {-9, -6, -4, 6}
range: {-6, -5, 8}

Explanation:

Step1: Identify domain (x-values)

Extract all first values from ordered pairs: $6, -6, -4, -9$. Organize in order: $\{-9, -6, -4, 6\}$

Step2: Identify range (y-values)

Extract all second values from ordered pairs: $8, 1, -5, -6$. Organize in order: $\{-6, -5, 1, 8\}$

Step3: Match to correct option

Compare domain and range to given choices.

Answer:

domain: $\{-9, -6, -4, 6\}$
range: $\{-6, -5, 1, 8\}$
