V X +2x +22 -5 For the function f(x) = x - 1 , find the following. (a) Evaluate lim f(x) and lim f(x), and then identify the horizontal asymptotes. X-+00 X - - 00 (b) Find the vertical asymptote. For the vertical asymptote x = a, evaluate lim f(x) and lim f(x). x-+ a- x-at (a) lim f(x) =] X-+00 lim f(x) = x- - 00 Identify the horizontal asymptotes. Choose the correct answer below. O A. The horizontal asymptotes is/ are y = (Use a comma to separate answers as needed.) O B. There are no horizontal asymptotes. (b) Find the vertical asymptote. For the vertical asymptote x = a, evaluate lim f(x) and lim f(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. X-a" x-at O A. The vertical asymptote is x= . The limits at this vertical asymptote are lim f(x) = and lim f(x)=. x-a x-at O B. There is no vertical asymptote
