horizontal asymptote is y = 1
Explanation:
A horizontal asymptote can be found when the degree of the
numerator is equal to the degree of the denominator of a
rational function.
In this question the degree of numerator and denominator are both
1 and so horizontal asymptote exists.
To establish it's equation take the ratio of leading coefficients.
y = 1/1 = 1 the graph shows that as
lim_(x→±∞) y = 1
