**drwls**, Friday, February 20, 2009 at 2:27amf^-1)(-3) is the value of x that you get when f(x) = -3. That value is 0.

g^-1(0) is the value of x that you get when g(x) = 0. That is also zero.

So (g^-1*f^-1)(-3) = 0

In functional form,

f^-1(x) = 8(x+3)

g^-1(x) = x^(1/3)

(g^-1*f^-1)(x) = [8(x+3)]^1/3

2(x+3)^1/3
