Question

Let f(x)=x^3-1 and g(x)=x^(1/3)+1.
Find: f(g(3))
f(g(x))
I can attempt to do the two other problems similar to this, but I am having trouble knowing how to plug this in.

Answer 1

\[f(g(x)) \implies (x^{1/3}+1)^3-1\] you take g(x) and plug it wherever there is an x in f(x) that's what it's saying.

Answer 2

Now you easily find f(g(3))

Answer 3

oh these two questions are separate ones that don't relate directly, but that works too?
