Answer
Explanation:
Step1: Recall horizontal - asymptote rules
For a rational function $y = \frac{f(x)}{g(x)}=\frac{a_nx^n+\cdots+a_0}{b_mx^m+\cdots + b_0}$, if $n = m$, the horizontal asymptote is $y=\frac{a_n}{b_m}$; if $n<m$, the horizontal asymptote is $y = 0$; if $n>m$, there is no horizontal asymptote.
Step2: Analyze $\frac{x^{2}+1}{x^{2}+2}$
Here $n = m=2$, $a_n = 1$, $b_m = 1$. So $y=\frac{1}{1}=1$. It has a horizontal asymptote at $y = 1$.
Step3: Analyze $\frac{x^{3}+1}{x^{2}+2}$
Here $n = 3$, $m = 2$, $n>m$. So it has no horizontal asymptote.
Step4: Analyze $\frac{x^{2}+1}{x^{3}+2}$
Here $n = 2$, $m = 3$, $n<m$. So it has a horizontal asymptote at $y = 0$.
Answer:
- a Horizontal asymptote at y=1
- No horizontal asymptote
- a Horizontal asymptote at y=0
