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

$\displaystyle f[g(s(x))] =$
$\displaystyle f[g(3x4)] =$
$\displaystyle f[\sin(3x4)] =$
$\displaystyle \sin^3(3x4) + 2$
