Does cancellation impact vertical asymptotes? Question: Let r(x)=(x2+x)/((x+1)(2x−4)). Does the graph has x=1 as one of its asymptotes? My reasoning: (x2+x)/((x+1)(2x−4))=x(x+1)/((x+1)(2x−4))=x/(2x−4) and so, it cannot have x=−1 as one of its asymptotes. However, what if I don't calcel and then say that −1 is a vertical asymptote? Will I be wrong?
