1.   State the domain of the relation {(1, 6), (-2, 3), (5, 7), (5, 9)}.
    A. {-2, 1, 5} B. {5}
    C. {-2, 1} D. {3, 6, 7, 9}
    Hint

  2.   State the domain of the relation whose graph is shown.
   
    A. {-2, -1, 2} B. {-2, -1, 0, 2}
    C. {0} D. {-1, 4, 1, 2}
    Hint

  3.   State the range of the function represented by the graph.
   
    A. {-1, 1, 2} B. {-1, 1, 2, 4}
    C. {1, 2, 4} D. {-2, -1, 0, 2}
    Hint

  4.   Determine the range for {(0, 1), (-3, 7), (4, -6), (5, 0)}.
    A. {3, 0, -4, -5} B. {-3, 0, 4, 5}
    C. {6, 0, -1, -7} D. {-6, 0, 1, 7}
    Hint

  5.   Is the relation {(3, 4), (3, 7), (-6, 4), (4,4)} a function? State why or why not.
    A. no; values in the domain have more than one value in the range.
    B. no; values in the range have more than one value in the domain.
    C. yes; values in the domain have one value in the range.
    D. yes; values in the domain have more than one value in the range.
    Hint
