Answer

Left : not a graph of a function Right: a graph of a function, domain [-3, 3], range: [-2, 3]

Work Step by Step

The left curve fails the Vertical Line Test (the line $x=0$ intersects it three times). It is not the graph of a function of x. The curve on the right passes the Vertical Line Test, so it is the graph of a function of x. The domain is [-3, 3] and the range is [-2, 3]
