Answer
The function
has a vertical asymptote at
and a horizontal asymptote at
.
Solution
-
Vertical Asymptote:The vertical asymptote occurs where the denominator is zero (and the numerator is not zero). Forset the denominator equal to zero:Thus, the vertical asymptote is
. -
Horizontal Asymptote:Since the degrees of the numerator and denominator are both 1, the horizontal asymptote is determined by the ratio of the leading coefficients. The numerator has a leading coefficient of 2, and the denominator has a leading coefficient of 1. Therefore:So, the horizontal asymptote is
.
The asymptotes for
are:
- Vertical asymptote:
- Horizontal asymptote:

Bonus Knowledge
To find the asymptotes of the function
, we first identify the vertical asymptote by setting the denominator equal to zero. Thus,
gives
as a vertical asymptote.
Next, we determine the horizontal asymptote by examining the degrees of the polynomial in the numerator and denominator. Since both the numerator and the denominator are linear (degree 1), the horizontal asymptote can be found by dividing the leading coefficients. This results in
as the horizontal asymptote.
So, the function has a vertical asymptote at
and a horizontal asymptote at
.
