Answer

The limit is undefined (approaches negative infinity). Explanation 1. Identify the highest power of ( ( \(x\) ) ) The highest power in the numerator is \(x^3\) and in the denominator is \(x^2\). 2. Divide each term by \(x^3\) Rewrite the expression as \(\frac{-4 - \frac{3}{x} - \frac{4}{x^2} + \frac{8}{x^3}}{-\frac{3}{x} - \frac{1}{x^2} + \frac{2}{x^3}}\). 3. Evaluate the limit as \(x \to \infty\) As \(x \to \infty\), terms with ( ( \(x\) ) ) in the denominator approach zero. Thus, the expression simplifies to \(\frac{-4}{0}\). 4. Conclude the behavior of the limit Since the denominator approaches zero while the numerator remains constant, the limit does not exist in a finite sense.
