Determine a value of m (if possible) for which f is continuous at x = 2. mx - 4 if x = 2 f ( X ) = x 2 if x = 2 Choose the correct answer below and, if necessary, fill in the answer box within your choi OA. m = O B. f'(2) exists for any chosen value of m O C. There is no value of m for which f (2) exists
