Let \(r(x)=\frac{P(x)}{Q(x)}\) is a rational function
The cut point of the function r(x) are the values of the x at which either
\(P(x)=0\) or \(Q(x)=0\)
To find the rational inequality use the test points between the successive cut points to find the interval that satisfies the inequality

One method of graphing rational functions that are reciprocals of polynomial functions is to sketch the polynomial function and then plot the reciprocals of the y-coordinates of key ordered pairs. Use this technique to sketch \(\displaystyle{y}={\frac{{{1}}}{{{f{{\left({x}\right)}}}}}}\) for each function.

\(a)f(x)=2x,\)

b)f(x)=\(\displaystyle{4}{x}^{{{2}}},\),

\({c}{)}{f{{\left({x}\right)}}}={x}^{{{2}}}-{1}\)

d) \(\displaystyle{f{{\left({x}\right)}}}={x}^{{{3}}}\)

(a) How do you find vertical asymptotes of rational functions? (b) Let s be the rational function \(\displaystyle{s}{\left({x}\right)}={\frac{{{a}_{{{n}}}{x}^{{{n}}}+{a}_{{{n}-{1}}}{x}^{{{n}-{1}}}+\cdots+{a}_{{{1}}}{x}+{a}_{{{0}}}}}{{{b}_{{{m}}}{x}^{{{m}}}+{b}_{{{m}-{1}}}{x}^{{{m}-{1}}}+\cdots+{b}_{{{1}}}{x}+{b}_{{{0}}}}}}\$\$\)
How do you find the horizontal asymptote of s? (c) Find the vertical and horizontal asymptotes of \(\displaystyle{f{{\left({x}\right)}}}={\frac{{{5}{x}^{{{2}}}+{3}}}{{{x}^{{{2}}}-{4}}}}\)

Do all rational functions have vertical asymptotes? Why or why not? If not, give an example of a rational function that does not have a vertical asymptote.

Investigate asymptotes of rational functions. Copy and complete the table. Determine the horizontal asymptote of each function algebraically. Function Horizontal Asymptote
\(\displaystyle{f{{\left({x}\right)}}}=\frac{{{x}^{{2}}-{5}{x}{4}}}{{{x}^{{3}}+{2}}}\)
\(\displaystyle{h}{\left({x}\right)}=\frac{{{x}^{{3}}-{3}{x}^{{2}}+{4}{x}-{12}}}{{{x}^{{4}}-{4}}}\)
\(\displaystyle{g{{\left({x}\right)}}}=\frac{{{x}^{{4}}-{1}}}{{{x}^{{5}}+{3}}}\)
