Question
Can you please answer the question below: Thanks.
![The image contains a mathematical expression representing a limit. The expression is formatted as follows:
\[
\lim_{{x \to -\infty}} \frac{{2x^4 + 5x + 1}}{{x^2 - 3x^4}}
\]
This is a calculus problem where you are tasked with finding the limit of the given rational function as \(x\) approaches negative infinity. The function is a fraction where the numerator is \(2x^4 + 5x + 1\) and the denominator is \(x^2 - 3x^4\).
### Key Points to Solve the Limit:
1. **Identify the Degrees of the Polynomials:**
- The highest degree term in the numerator is \(2x^4\).
- The highest degree term in the denominator is \(-3x^4\).
2. **Comparing Degrees:**
- Since the degree of the numerator and the denominator is the same (both are 4), the limit largely depends on the coefficients of these terms.
3. **Simplifying the Expression:**
- Focus on the leading terms for simplicity:
\[
\lim_{{x \to -\infty}} \frac{{2x^4}}{{-3x^4}} = \frac{2}{-3} = -\frac{2}{3}
\]
Therefore, the limit of the expression as \(x\) approaches negative infinity is \(-\frac{2}{3}\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F877dc177-9e71-4d70-b3c8-b42ecf376b51%2F482bec47-8615-40ef-807e-f8f237bd8ce4%2Fxks6fas_processed.jpeg&w=3840&q=75)
