# How do you find the vertical, horizontal or slant asymptotes for 3/(2x-1)?

Mar 13, 2016

vertical asymptote $x = \frac{1}{2}$
horizontal asymptote y = 0

#### Explanation:

Vertical asymptotes occur as the denominator of a rational function tends to zero. To find the equation let the denominator equal zero.

solve : 2x - 1 = 0 → $x = \frac{1}{2} \text{ is the asymptote }$

Horizontal asymptotes occur as lim_(x→±∞) f(x) → 0

If the degree of the numerator is less than the degree of the denominator, as in this case , numerator degree 0 , denominator degree 1.
Then the equation of asymptote is always y = 0
