The domain of a function is the set of all possible input values (x-values), which must be unique. The given table shows the x-values as -3, -7, 1, -8, -7, and 1. However, since -7 and 1 are repeated, they are only listed once in the domain, making the correct domain \{-3, -7, 1, -8\}. The range of a function is the set of all possible output values (y-values), and duplicates are also listed only once. The y-values given are 7, 1, 5, 4, 8, and 4, but since 4 is repeated, it is only listed once, making the correct range \{7, 1, 5, 4, 8\}.
