The expression $h(g(x))$ represents the composition of two functions, where the function $h$ is applied to the result of the function $g(x)$.

In more detail:

• First, you evaluate $g(x)$, which gives some output.
• Then, you take this output and use it as the input for the function $h$.

Mathematically: $h(g(x)) = h(y), \text{ where } y = g(x).$ The result depends on the specific definitions of $h$ and $g$. If you provide the formulas for $h(x)$ and $g(x)$, I can give you the exact result.

Would you like to provide those functions, or is there something more specific you're asking about?

Here are 5 related questions that could expand on this:

1. What are the specific forms of $h(x)$ and $g(x)$?
2. How do you differentiate a composite function like $h(g(x))$?
3. What are the properties of composite functions?
4. How do you find the inverse of a composite function?
5. What happens when you compose the same function multiple times, like $h(h(x))$?

Tip: When differentiating composite functions, remember to use the chain rule!
