    you have to evaluate you function at points: x=-4, x=3, first

    At -4=13 and at 3=6

    ok! now you have to compute the first derivative of your function

    that's right! Now your first derivative is equal to zero at x=3/2, right?

    Yes

    nevertheless x=3/2 is not a local point of maximum

    So how would I find it

    you have to establish the answer using the values above, namely f(-4) and f(3)

    So I would plug it into the derived equation?

    no, your values are: f(-4)=13, and f(3)= 6 so what is the greatest value?

    f(-4)=13

    correct! so the absolute maximum value is at x=-4, ant it is 13
