It looks like you're asking for the long-run behavior of a function as $x \to \infty$, but I need more information. Could you provide the specific function you're working with? For example, are you asking about a polynomial, rational, exponential, or trigonometric function?

Once I have the function, I can help analyze its long-run behavior, also known as the limit or asymptotic behavior as $x$ approaches infinity (or negative infinity).

Let me know!

Here are 5 follow-up questions related to long-run behavior:

1. Are you working with a specific function or just a general type of function?
2. Do you want to find horizontal asymptotes or the behavior as $x \to \infty$?
3. Are there any terms involving $e^x$, $\ln(x)$, or trigonometric functions in your problem?
4. Is this part of a calculus problem involving limits or derivatives?
5. Would you like to analyze behavior as $x \to -\infty$ as well?

Tip: For rational functions, the degree of the numerator and denominator often determines the long-run behavior!
