Question
![**6. Guess the smallest \( n \) such that the function**
\[
\frac{x^4 - x^3 + 5x + 3 \log x}{2x^2 + x + 1}
\]
**is \( O(x^n) \) and then use the definition of \( O \) to prove your conjecture.**
**Explanation:**
The problem requires determining the smallest power \( n \) such that the given function is bounded by \( O(x^n) \) in the context of asymptotic notation, which describes the behavior of functions as they approach a particular limit or infinity. The numerator of the function is dominated by the largest term \( x^4 \), while the denominator is dominated by \( 2x^2 \). The objective is to assess the dominant term in the expression and confirm the asymptotic behavior analytically.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F341515a7-9f2b-49dc-a023-366552e2ebc5%2F9cf83fb9-87ae-414f-bbdb-adc7c96aa13d%2F8rkqj9d_processed.jpeg&w=3840&q=75)
