Find the horizontal and vertical asymptote(s) of LaTeX:  \displaystyle f(x) = \frac{x^{2} + 7 x - 120}{10 x^{2} + 10 x - 20} , if they exist.

The degree of the numerator is the same as the degree of the denominator, so the horizontal asymptote is the ratio of the leading coefficients LaTeX:  \displaystyle y=\frac{1}{10} . The vertical asymptotes are the zeros of the denominator. LaTeX:  \displaystyle 10 x^{2} + 10 x - 20=0 \iff 10 \left(x - 1\right) \left(x + 2\right)=0 . The vertical asymptotes are LaTeX:  \displaystyle x=-2 and LaTeX:  \displaystyle x=1 .
