To find vertical asymptotes, you must find the zeros of the denominator
Ex. $\frac{3}{x-2}$
$x = 2
$

To find horizontal asymptotes, compare the degree of the numerator and the degree of the denominator of the rational function:

1. If the degree is the numerator < degree of the denominator, then the horizontal asymptote is 0

Ex. $\frac{3}{x-2}$
horizontal asymptote = 0

2. If the degree is the numerator = degree of the denominator, then the horizontal asymptote is:

$\frac{leading.coefficient.of.numerator}{leading.co efficient.of. denominator}$

ex. $\frac{2x-2}{3x+4}$
horizontal asymptote = $\frac{2}{3}$

3. If the degree is the numerator > degree of the denominator, then there is no horizontal asymptote

ex. $\frac{2x^2-2}{3x+4}$
There is no horizontal asymptote
