Determine the average velocity of the particle over the time interval [1 , 3]. 1. average vel. = 16 ft/sec 2. average vel. = 19 ft/sec 3. average vel. = 18 ft/sec 4. average vel. = 17 ft/sec 5. average vel. = 15 ft/sec CalC2b01a 48:02, calculus3, multiple choice, > 1 min, wording-variable. 003 Suppose lim x 5 f ( x ) = 4 . Consider the following statements: A. As f ( x ) approaches 4, x approaches 5. B. f is defined on ( a, 5) (5 , b ) for some a < 5 < b . C. Range of f need not contain 4. Which of these statements are true without further restrictions on f ? 1. B and C only 2. C only Create assignment, 59515, Practice 1, Sep 19 at 2:12 pm 2 3. all of them 4. B only 5.
