X+4 Use the definition of continuity to determine whether f(x) = - is continuous at 4. X - 4 Is f continuous at 4? Select the correct choice below and, if necessary, fill in the answer boxes to complete your answer choice. O A. No. Because f(4) does not exist. O B. Yes. Because f(4) = and lim f(x) = X-+4 O C. No. Because f(4) = and lim f(x) = and f(4) * lim f(x). X-+4 X-+4
