{(5, 2), (-5, 0), (6, 2), (2, 7)}



{0, 2, 7}

{-5, 0, 2, 5, 6, 7}

{-5, 2, 5, 6}

Answer 1

The domain is the collection of the inputs, the range is the collection of the outputs. Inputs are usually x values; outputs are usually y values. Gather the values of y, delete any duplicates, and you have the range.
