To find: Check whether it has horizontal asymptote find the asymptote if it has and give the reason if there is no horizontal asymptote.
Yes, there is a horizontal asymptote at
Given:
The model is
Concept used:
To find the horizontal asymptote find the degree of the numerator and denominator.
Three cases can arise.
- When the degree of numerator is less than the degree of the denominator.
- When the degree of numerator is equal to the degree of the denominator.
- When the degree of numerator is greater than the degree of the denominator.
Then the horizontal asymptote will be
Then the horizontal asymptote will be
Then there will be no horizontal asymptote.
Calculation:
The model is
The degree of numerator is equal to the degree of the denominator.
The horizontal asymptote is as shown below.
Conclusion:
Yes, there is a horizontal asymptote at

- Calculate these limits. If the limit is ∞ or -∞, write infinity or-infinity. If the limit does not exist, write DNE: Hint: Remember the first thing you check when you are looking at a limit of a quotient is the limit value of the denominator. 1. If the denominator does not go to 0, you should be able to right down the answer immediately. 2. If the denominator goes to 0, but the numerator does not, you will have to check the sign (±) of the quotient, from both sides if the limit is not one-sided. 3. If both the numerator and the denominator go to 0, you have to do the algebraic trick of rationalizing. So, group your limits into these three forms and work with them one group at a time.
