the problem is:
i need to identity the vertical and horizontal asymptote as well as the domain
so i got, horizontal asympt y=1
vertical asymptote = 2,1
and domain is all numbers except 2 and 1
to obtain the vertical asymptote i set the denominator to equal zero, but apprently i did something wrong somewhere because the answer says that the vertical asymptote CANNOT be 2. is there another way to obtain the vertical asymptote? can i use this method for all problems?
why can the vertical asymptote NOT be 2?
