# Math Help - combining functions

1. ## combining functions

I seem to run into another problem in my homework. (I could see it coming

If:
f (x) = 3(x+1)^2 (the last 2 means square)
g (x) = (2/x) - 1

what is (f *g)(x) (multiplication)

thank you

$(f*g)(x)=f(x)*g(x)=3(x+1)^2 * (\frac 2x-1)=3(x+1)^2 * \frac{2-x}{x}$
