x² - 64 Follow the steps for graphing a rational function to graph the function H(x) = x* -81 Determine the behavior of the graph on either side of any vertical asymptotes, if one exists. Select the correct choice below and, if necessary, fill in the answer box(es) tr complete your choice. and - 00 on the other. It approaches either oo or - 0o on both sides of the asymptote(s) at x = O A. It approaches oo on one side of the asymptote(s) at x= (Type integers or simplified fractions. Use a comma to separate answers as needed. Type each answer only once.) O B. It approaches either co or - 00 on both sides of the asymptote(s) at x = (Type integers or simplified fractions. Use a comma to separate answers as needed. Type each answer only once.) O C. It approaches o on one side of the asymptote(s) at x = (Type integers or simplified fractions. Use a comma to separate answers as needed. Type each answer only once.) and - 00 on the other. O D. There is no vertical asymptote. Determine the horizontal asymptote(s), if one exists. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The function has one horizontal asymptote, (Type an equation.
