Problem
Find $f(g(x))$. \[ \begin{array}{l} f(x)=x^{3} \quad g(x)=|x+1| \\ f(g(x))=(|[?]+\square|)^{3} \\ \end{array} \]
Solution
Step 1 ：Given functions are \(f(x)=x^{3}\) and \(g(x)=|x+1|\).
Step 2 ：We need to find \(f(g(x))\).
Step 3 ：Substitute \(g(x)\) into \(f(x)\) to get \(f(g(x)) = (|x+1|)^3\).
Step 4 ：So, the final answer is \(f(g(x)) = \boxed{(|x+1|)^3}\).
