### Calculus Limits Problems

**Problem e.**  
Evaluate the limit:  
\[
\lim_{x \to \infty} \frac{5x^3 + 8x^2 - 4}{10x^3 + 3x + 1}
\]

**Problem f.**  
Evaluate the limit:  
\[
\lim_{x \to -\infty} \frac{16x^5 + 7x^2}{12x^5 + \sqrt{16x^{10}} + 1}
\]

**Problem g.**  
Evaluate the limit:  
\[
\lim_{x \to 0^+} x^2 \sin\left(\frac{1}{x}\right)
\]
(*Hint: Use the Squeeze Theorem*)

---

These problems focus on evaluating limits of rational functions and trigonometric expressions. Problem g hints at using the Squeeze Theorem to find the limit as \( x \) approaches 0 from the positive side.
