vertical asymptote at

# x = -1/2#

horizontal asymptote at# y = 1/2 #

#### Explanation:

Vertical asymptotes are found when the denominator of

the rational function is zero.

This will occur when 2x + 1 = 0 , hence 2x = - 1

vertical asymptote is :

# x = -1/2 # [ Horizontal asymptotes can be found when the degree of

the numerator and the degree of the denominator are equal.]

In this question they are both of degree 1 and so a

horizontal asymptote exists.

The asymptote is found by taking the ratio of leading

coefficients.horizontal asymptote is ;

# y = 1/2 #
