    1/3 or 0.33

    Step-by-step explanation:

    Put - 2 where x is in the function definition and do the arithmetic.

    g (-2) = 3^ (-2/2)

    = 3^ (-1)

    g (-2) = 1/3

    Of course, you know that the decimal equivalent of the fraction 1/3 is the repeating decimal 0.33333 ... Rounding this to 2 decimal places gives you ...

    g (-2) ≈ 0.33
