Answer:
the answer is the first option--Domain {2, 4, 8, 1, -5}; Range {0, -2, 6}
Explanation:
your domain is your set of all "x" values
your range is your set of all"y" values
**your range has "y" values that repeat, DO NOT write two of the same "x" or "y" values even if they appear in the domain or range more than once. In your "x" values no numbers repeat so you should write all five {2, 4, 8, 1, -5}, making the domain. In your "y" values the 0 and the 2 repeat twice each. You only write each ONCE. So your set for the range should ONLY be {0, -2, 6}.
