How to find the asymptotes of #f(x) = (x+6)/(2x+1)# ?
This function has vertical asymptote
To check if a rational function has a vertical asymtote(s) you have to look for zeroes of the denominator.
In this case there is one zero
To look for the horizontal asymptotes you have to calculate
In this example we have:
The limits are finite and equal, so
