Not a function. Domain: [-4, 4] Range: [-3, 3]

Work Step by Step

This graph is not a function because it fails the vertical line test -- a vertical line can pass the graph in two points, indicating that there can be two different $y$ values for one $x$ value (not a function). We can see that the domain consists of values between -4 and 4 (inclusive) and the range consists of values between -3 and 3 (inclusive). Domain: [-4, 4] Range: [-3, 3]
