Caluculus question

x2- Bx +7 Follow the steps for graphing a rational function to graph the function Fix) = x- 2x +1 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 boxes) to complete your choice. A. It approaches co on one side of the asymptote(s) at x = and - co on the other. It approaches either co or - co 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 B. It approaches co on one side of the asymptote(s) at x = and - oo on the other. (Type an integer or a simplified fraction. Use a comma to separate answers as needed. Type each answer only once.) O C. It approaches either co or - Do on both sides of the asymptote(s) at x = (Type an integer or a simplified fraction. Use a comma to separate answers as needed. Type each answer only once. ) O D. The function has no vertical asymptote
