The expression you've provided is the beginning of a limit problem, specifically as $x \to \infty$. To fully evaluate this, the function or expression inside the limit must be provided. For example:

1. $\lim_{x \to \infty} \frac{1}{x}$ evaluates to 0.
2. $\lim_{x \to \infty} (x^2)$ evaluates to $\infty$.
3. $\lim_{x \to \infty} \frac{1}{x^2 + 1}$ evaluates to 0.

Could you please provide the complete expression so I can assist you further?

Would you like more details on how limits behave at infinity or have any other questions?

Here are five related questions:

1. What is the limit of $\frac{1}{x}$ as $x \to 0^+$?
2. What is the behavior of exponential functions as $x \to \infty$?
3. How do you evaluate limits of rational functions as $x \to \infty$?
4. What is L'Hopital's Rule and when is it used in limits?
5. How do limits at infinity relate to horizontal asymptotes?

Tip: When dealing with limits at infinity, always consider the highest degree of terms in both the numerator and denominator if working with rational functions.
