Answer:
Domain: {1, -3, 6, -2}
Range: {2, 5, 6, 0, 2}
Step-by-step explanation: The domain is the x-coordinate. These "domains", however; cannot be repeated.
The range is the y-coordinate and can be repeated.
Think about the vertical line test. When you put a straight line through an existing segment, each x-coordinate will be the same and is not considered a function.
