Question

what are the domain and range of this function?
there is a coordinate grid with several purple points plotted. then four options for domain and range are given:

1. domain: {-2, -1, 1, 2}, range: {-3, -2, 1, 4}
2. domain: {-2, -1, 0, 1, 2}, range: {-3, -2, -1, 4}
3. domain: {-2, -1, 1, 2}, range: {-3, -2, -1, 4}
4. domain: {-2, -1, 0, 1, 2}, range: {-3, -2, 1, 4}

Explanation:

Step1: Identify domain (x-values)

List all x-coordinates of points: $x = -2, -1, 1, 2$

Step2: Identify range (y-values)

List all y-coordinates of points: $y = -3, -2, 1, 4$

Answer:

domain: $\{-2, -1, 1, 2\}$
range: $\{-3, -2, 1, 4\}$
