    Answer:

    Step-by-step explanation:

    Unclear.  Did you mean f(x) = 2^(x + 3)?  If so, the parentheses are mandatory.

    Assuming that f(x) = 2^(x + 3) is correct, then:

    a) f(2) = 2^(2 + 3) = 2^5 = 32

    b) f'(x) = 2^(x + 3)*(x + 3)’ = 2^(x + 3)(1) = 2^(x + 3)

    c) f”(x) = 2^(x + 3) (same as in (b)), so that:

       f”(12) = 2^15
