Answer
Explanation:
Step1: Analyze degree of numerator and denominator for $\frac{x^{3}+1}{x^{2}+2}$
Degree of numerator is 3, degree of denominator is 2. As $x\to\pm\infty$, since degree of numerator > degree of denominator, $y\to\pm\infty$.
Step2: Analyze degree of numerator and denominator for $\frac{x^{2}+1}{x^{3}+2}$
Degree of numerator is 2, degree of denominator is 3. As $x\to\pm\infty$, since degree of numerator < degree of denominator, $\lim_{x\to\pm\infty}\frac{x^{2}+1}{x^{3}+2}=0$.
Step3: Analyze degree of numerator and denominator for $\frac{x^{2}+1}{x^{2}+2}$
Degree of numerator and denominator is 2. Leading - coefficient of numerator is 1, leading - coefficient of denominator is 1. As $x\to\pm\infty$, $\lim_{x\to\pm\infty}\frac{x^{2}+1}{x^{2}+2}=\lim_{x\to\pm\infty}\frac{1+\frac{1}{x^{2}}}{1 + \frac{2}{x^{2}}}=1$.
Answer:
For $\frac{x^{3}+1}{x^{2}+2}$, $y\to\pm\infty$ as $x\to\pm\infty$; for $\frac{x^{2}+1}{x^{3}+2}$, $y\to0$ as $x\to\pm\infty$; for $\frac{x^{2}+1}{x^{2}+2}$, $y\to1$ as $x\to\pm\infty$
