Find the horizontal and vertical asymptote(s) of LaTeX:  \displaystyle f(x) = \frac{x^{2} + 4 x - 96}{7 x^{2} + 21 x + 14} , 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}{7} . The vertical asymptotes are the zeros of the denominator. LaTeX:  \displaystyle 7 x^{2} + 21 x + 14=0 \iff 7 \left(x + 1\right) \left(x + 2\right)=0 . The vertical asymptotes are LaTeX:  \displaystyle x=-2 and LaTeX:  \displaystyle x=-1 .
