Unformatted text preview: silva (jrs4378) – Hw 13 – gualdani – (56455) 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Consider the following properties that a func- tion f might have: A. f ′ ( x ) > 0 for all x ; B. f is 1- 1; C. graph of f passes vertical line test. Which properties always ensure that f has an inverse f − 1 ? 1. A only 2. none of them 3. A and C only 4. all of them 5. B and C only 6. A and B only 7. B only 8. C only 002 10.0 points If the graph of f is 4 8- 4- 8 4 8- 4- 8 which of the following is the graph of f − 1 ( x )? 1. 4 8- 4- 8 4 8- 4- 8 2. 4 8- 4- 8 4 8- 4- 8 3. 4 8- 4- 8 4 8- 4- 8 4. 4 8- 4- 8 4 8- 4- 8 silva (jrs4378) – Hw 13 – gualdani – (56455) 2 5. 4 8- 4- 8 4 8- 4- 8 003 10.0 points Find the inverse function, f − 1 , for f when f ( x ) = radicalbig 36- x 2 , ≤ x ≤ 6 . 1. inverse doesn’t exist 2. f − 1 ( x ) = radicalbig 36- x 2 ,- 6 ≤ x ≤ 6 3. f − 1 ( x ) = radicalbig x 2- 36 ,- 6 ≤ x ≤ 6 4. f − 1 ( x ) = radicalbig 36- x 2 , ≤ x ≤ 6 5. f − 1 ( x ) = 1 √ 36- x 2 , ≤ x < 6 004 10.0 points Find the inverse of f ( x ) = 1 + 3 x 6- 5 x ....
