Answer

Not a function domain: [-1, 1] range: [-1, 1]

Work Step by Step

This is not a function, for it fails the vertical line test. Since the domain extends from -1 to 1, this defines the range. Similarly, the range is always between -1 and 1, with no gaps in the line, so [-1,1] defines the range as well.
