Answer:

Domain: x : {5, 10, 15, 20)

Range: y : {-3, -1, 1, 3}

Explanation:

The domain is the x-coordinates.

The range is the coordinates.

In point (5, 1), the x-coordinate is 5 while the y-coordinate is 1.

^^Now using this, we can figure out the domain and range:

Domain: x : {5, 10, 15, 20)

Range: y : {1, 10, -3, -1} ==> wait this isn't in order

We can fix the order:

Range: y : {-3, -1, 1, 3} ==> this is better

Domain: x : {5, 10, 15, 20)

Range: y : {-3, -1, 1, 3}
