22. If f(x) has a continuous derivative on (1,7), f'(1) = 3 and f'(7) = -5, which of the following statements is necessarily true? (A) f(x) = 0 has at most one solution between 1 and 7 (B) f(x) = 0 has at least one solution between 1 and 7 (C) the graph of f(x) has a vertical asymptote between 1 and 7 (D) the graph of f(x) has a horizontal tangent between 1 and 7 (E) none of (A) to (D)
