    Answer:

    The value of f(2) would be -40.

    Step-by-step explanation:

    Given function is,

    f(x) = 2x^3 - 3x^2 - 18x - 8

    Substituting x = 2 in the above function,

    We get,

    f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8

    =2(8) - 3(4) - 36 - 8

    =16 - 12 - 44

    \implies f(2)= -40

    Hence, the value of f(2) would be -40.
