Based on the graph you provided, it seems like there are three points plotted: (−2,6)(-2, 6)(−2,6), (0,6)(0, 6)(0,6), and (1,0)(1, 0)(1,0).

To answer the questions:

Domain (the set of all possible x-values):
    The x-values from the points are −2-2−2, 000, and 111.
    So, the domain is {−2,0,1}\{-2, 0, 1\}{−2,0,1}.

Range (the set of all possible y-values):
    The y-values from the points are 666 and 000.
    So, the range is {0,6}\{0, 6\}{0,6}.

Set notation:

The domain is
