Given that $h'(x) = g(x) + f(x)$, we can interpret this equation as the derivative of some function $h(x)$, which is the sum of two functions $g(x)$ and $f(x)$.

If you want to proceed with further operations or analyses, there are several directions you could go, depending on what you're looking for. Here are a few possibilities:

1. Integrating both sides: To find $h(x)$, we could integrate the right-hand side, $g(x) + f(x)$. $h(x) = \int (g(x) + f(x)) \, dx = \int g(x) \, dx + \int f(x) \, dx$ This would provide the original function $h(x)$, up to a constant of integration.

2. Analyzing specific forms of $g(x)$ and $f(x)$: If you know the explicit forms of $g(x)$ and $f(x)$, we could solve for $h(x)$ directly or explore other properties.

3. Applying to specific problems: This derivative relationship could be useful in problems related to rates of change, optimization, or areas under curves.

Would you like to proceed with any specific approach, or do you need more details about any of these steps?

Here are 5 possible next questions:

1. What are the explicit forms of $g(x)$ and $f(x)$?
2. Would you like to integrate both sides to find $h(x)$?
3. Are there any initial conditions or boundary conditions to find the constant of integration?
4. Do you need to analyze the behavior of $h(x)$, such as finding critical points or inflection points?
5. Should we explore how this derivative is applied in a particular context, such as physics or economics?

Tip: When dealing with sums of functions in calculus, remember that the derivative of a sum is simply the sum of the derivatives!
