Answer:

Domain = -3, -1, 1.

Explanation:

Let's find Domains of x-coordinates of the following.

1) (-3, -2) => (x = -3)

2) (-3, 0) => (x = -3)

3) (-1, 2) => (x = -1)

4) (1, 2) => (x = 1)

Hence, value of x = domain .

These x values lie on the x-coordinates .

Answer: D: x = {-3, -1, 1}

Explanation:

Domain refers to the x-values of the coordinates.

Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.

(-3, -2) --> x = -3

(-3, 0) --> x = -3 already listed above so no need to list it again

(-1, 2) --> x = -1

(1, 2) --> x = 1

the x-values are: -3, -1, & 1

so the domain is: x = {-3, -1, 1}
