Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points Determine f ( e ) when f ( x ) = x 2 (6 + (ln x ) 3 ) . 1. f ( e ) = 15 e 2. f ( e ) = 16 e 3. f ( e ) = 13 e 4. f ( e ) = 14 e 5. f ( e ) = 17 e correct Explanation: Using the Product and Power rules we see that f ( x ) = 2 x (6 + (ln x ) 3 ) + 3 x 2 (ln x ) 2 x = x (12 + 2(ln x ) 3 + 3(ln x ) 2 ) . At x = e , therefore, f ( e ) = 17 e . 002 10.0 points Use calculus to determine which one of the following could be the graph of f when f ( x ) = x- 2 ln parenleftBig x- 2 2 parenrightBig- 6 . 1. 2. correct 3. 4. 5. vu (tv2894) Homework 21 (Section 7.4) miner (55096) 2 6. Explanation: Since the graph of y = ln x has a vertical asymptote at x = 0 and ln x is defined only for x > 0, the graph of f will have a vertical asymptote at...
