Multiple-choice questions may continue on the next column or page – fnd all choices be±ore answering. 001 10.0 points Suppose lim x 5 f ( x ) = 4 . Which o± these statements are true without ±urther restrictions on f ? A. Range of f need not contain 4 . B. f is deFned on ( a, b ) for some a < 5 < b . C. As f ( x ) approaches 4 , x approaches 5 . 1. B and C only 2. A and C only 3. A and B only 4. None o± them 5. A only 6. All o± them 7. B only 8.
