    A function is a set of ordered pairs in which no two ordered pairs have the same first number. So is it a function?

    Good job. The domain is the set of x values and the range is the set of y values.

    So put them in order (don't list any number twice), put braces around them and that's your domain.....the set of x values. Do the same with the y values and that will be the range.
