Question

what are the domain and range of this function?
(-1, 10)
(4, -5)
(10, 9)
(6, 6)

domain: {-1, 4, 6, 10}
range: {-5, 6, 9, 10}

domain: {-1, 4, 6}
range: {-5, 6, 10}

domain: {-1, 4, 6}
range: {-5, 6, 9, 10}

domain: {-1, 4, 6, 10}
range: {-5, 6, 10}

Explanation:

Step1: Identify domain (x-values)

From the ordered pairs $(-1, 10), (4, -5), (10, 9), (6, 6)$, collect all first values: $\{-1, 4, 10, 6\}$ (sorted as $\{-1, 4, 6, 10\}$)

Step2: Identify range (y-values)

From the ordered pairs, collect all second values: $\{10, -5, 9, 6\}$ (sorted as $\{-5, 6, 9, 10\}$)

Step3: Match to options

Compare the domain and range to the given choices.

Answer:

domain: $\{-1, 4, 6, 10\}$
range: $\{-5, 6, 9, 10\}$
