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}
