Unformatted text preview: (b) Find the domain of C . You should be able to do this by common sense. (c) Compute C ( x ). (d) Graph C ( x ). (e) Compute the range. (This could be tough. Try to get close. A graphing calculator might help.) 1 (f) What x causes the least output? (This could be tough. Try to get close. A graphing calculator might help.) (g) What is the least output? Hints and Answers 1. Answer (c) is in your book. The others are pretty easy once you know part (c). 2. Same as above. 3. For part (c), side length is l ( d ) = d/ 2 and area is A ( d ) = d 2 / 2. 4. Book has part (c). 5. Book has part (c). Domain is 0 < x < 7 in. (Think about it!). Range is 0 < V 6- 93 / 3 385 . 7 in 3 . The is required. V ( x ) = 360 in 3 when x = 2 in or x = 8- 19 3 . 641 in. 2...
