Answer: Domain: -2<=x<=2
Range: -2<=y<=2
Not a function
Explanation:
Domain: x goes from -2 to 2
-2<=x<=2
Range: y goes from -2 to 2
-2<=y<=2
Not a function since there are several y-coordinates that have the same x-coordinate, so the graph doesn't pass the vertical line test. Example: (0, -2) and (0, 2).
