    Homework help

    Hey I usually dont have trouble with my homework but my precalculus instructor gave us this for home work and I can't figure it out.

    f(x) = x^3 + 2, g(x) = sin(x), s(x) = 3x - 4

    and the question looks like this: (f o g o s)(x) i really don't remember this stuff from high school but I tired and this is what I got:

    f(g(s(x))) >> f(g(3x - 4)) >> f(3sin(x) - 4) >> (3sin(x) - 4)^3 - 2

    thats all I could do, im not too sure if im right. If anyone could shed some light on this problem i'd appreciate it very much.

    thanks

    f[g(s(x))] =

    f[g(3x-4)] =

    f[\sin(3x-4)] =

    \sin^3(3x-4) + 2
