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

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

  3.   Express the relation whose graph is shown as a set of ordered pairs.
   
    A. {(1, 1), (-2, 2), (-3, -2), (-4, 3)}
    B. {(1, 1), (2, -2), (-3, -2), (-4, 3)}
    C. {(1, 1), (-2, 2), (-2, -3), (3, -4)}
    D. {(1, 1), (2, -2), (2, -3), (-3, 4)}
    Hint

  4.   Which graph represents a function?
    A. B.
    C. D.
    Hint

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