Answer:
Option b is right.
Step-by-step explanation:
A function is given as
Limit is to be found out for x tends to infinity.
We find that numerator and denominator has the same degree.
HEnce a horizontal asymptote exists
COefficients of leading terms are 1 and 1 respectively
Asymtote would be y =1/11 = 1
Alternate method:
When x tends to infinity, 1/x tends to 0
by dividing both numerator and denominator by square of x.
Now take limit as 1/x tends to 0
we get
limit is y tends to 1/1 =1
Hence horizontal asymptote is y =1
