How To Find Horizontal Asymptotes?
The horizontal asymptote of a rational function can be found out by looking at the degrees of the given numerator and denominator.
How to Find?
- If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote at y = 0.
- If the degree of the numerator is greater than the degree of the denominator by one, then no horizontal asymptote that means a slant asymptote.
Another way of finding a horizontal asymptote is by dividing N(x) by D(x). If the resultant quotient is constant, then y = this constant is the equation of a horizontal asymptote.
