Instructions: Please write complete solutions to the following problem using complete sentences and proper grammar. 1. (2.5 points) When is the vertical line x = a a vertical asymptote of the graph of y = f(x)? 2. (2.5 points) Let f(x) = (x-2)(1+1)(1+3) x+1 Find all vertical asymptotes for the graph of y = f(x). State why each is a vertical asymptote. (Hint: Theorem: Locating Vertical Asymptotes of Rational Functions.)
