Find the horizantal asymptote :
\To find horizontal asymptote, first find the degree of the numerator and degree of the denominator.
\Degree of the numerator and degree of the denominator
.
Since the degree of numerator is less than the degree of the denominator, the function has horizontal asymptote, at .
