    Your work has nothing to do with evaluating g(3a), so, no, you have not gotten it right.

    Fast Eddie's post shows you the answer.

    Clearly, it is not 2.

    Do you understand functions?

    g(3a) is a symbol that represents the quantity we get when we evaluate g(x) at x = 3a.

    We evaluate g(3a) by replacing each symbol x with the quantity 3a, and simplifying.

    Once we know the expression for g(3a), we add one to it to answer the exercise.

    Then please tell me exactly which parts of Fast Eddie's solution that you do not understand, and I will explain.

    Are you supposed to simplify what?

    Please show your work.

    OOP! for the last entry. I forgot the 9...
    do i simplify this?

    Oh, I see.

    No.

    No simplification is necessary because Fast Eddie gave you the simplified result. In other words, the final answer cannot be simplified any further.

    So, don't you fret about that.

    You can copy Fast Eddie's work onto your paper and turn it in without being concerned over losing any credit for failing to simplify.

    ANOTHER SATISFIED CUSTOMER!



    PS: DO NOT COPY THE LINE THAT READS, "OOP! for the last entry. I forgot the 9..."
