Answer:
A. Domain: {-8, -6, -4, -2, 0} Range: {2}
Step-by-step explanation:
The domain of a function is the x values, the range is the y values. you order them in either greatest to least or least to greatest (keep this consistent in both domain and range values). also, if a value repeats, only list it once (this is why the range is {2} rather than {2, 2, 2, 2, 2} )
