    Answer:

    D

    Step-by-step explanation:

    Given that f(x) has domain { 2, 4, 7 }

    Substitute the values from the domain into f(x) for the range

    f(2) = 2² – 5 = 4 – 5 = – 1

    f(4) = 4² – 5 = 16 – 5 = 11

    f(7) = 7² – 5 = 49 – 5 = 44

    Thus the range is { – 1, 11, 44 } → D
