Determine the vertical asymptote(s) of the function. If none exists, state that fact. x+4 f(X) = x - 12x + 32x . . . Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The function has three vertical asymptotes. The leftmost asymptote is the middle asymptote is , and the rightmost asymptote is (Type equations.) O B. The function has one vertical asymptote, . (Type an equation.) O C. The function has two vertical asymptotes. The leftmost asymptote is and the rightmost asymptote is (Type equations.) O D. The function has no vertical asymptotes
