Yes, the function $g(x) = (2x + 1)^4$ is a composite function. A composite function is formed when one function is applied to the result of another function.

For $g(x) = (2x + 1)^4$, we can identify the "inner" and "outer" functions as follows:

• Inner function: $u(x) = 2x + 1$
• Outer function: $h(u) = u^4$

The composite function $g(x)$ can be expressed as $g(x) = h(u(x)) = (u(x))^4 = (2x + 1)^4$.

Here are 5 related questions to expand on this topic:

1. What is the derivative of the composite function $g(x) = (2x + 1)^4$?
2. How do you differentiate composite functions using the chain rule?
3. Can you decompose more complex functions into their inner and outer parts?
4. What happens if the inner function is more complicated, such as a trigonometric function?
5. How do you find the second derivative of a composite function?

Tip: When dealing with composite functions, the chain rule is a powerful tool to differentiate them efficiently.
