5. Find the domain of f(x) - 10 - V3 - x 6. An electronics company produces a car stereo for which the variable cost is $5.60 and the fixed costs are $24,000. The product sells for $99.50. Write the total cost C as a function of the number of units produced and sold, x. Write the profit P as a function of the number of units produced and sold, x. In Exercises 7 and 8, determine algebraically whether the function is even, odd, or neither. 7. f(x) = 213 - 3x 8. f(x) - 3x + 5x2 In Exercises 9 and 10, determine the open intervals on which the function is increase ing, decreasing, or constant. 9. h(x) = x4 - 2x2 10. g(1) = |7 + 2 - |2 - 21 In Exercises 11 and 12, use a graphing utility to graph the functions and to approximate (to two decimal places) any relative minimum or relative maximum values of the function. 11. f(x) =-x3- -5x2 + 12 12. f ( x) = $5 - x3 + 2 In Exercises 13-15, (a) identify the parent function f, (b) describe the sequence of transformations from f to g, and (c) sketch the graph of g. 13. g(x) =-2(x - 5)3 + 3 14. g(x) V-x - 7 15. g (x) - 41-x| - 7 16. Use the functions f(x) = x} and g(x) - V2 - x to find the specified function and its domain. (a) (f- g)(x) ( b ) (- ) ( ) ( c ) ( f . 8 ) ( x ) ( d ) ( 8 . f ) ( x ) 9 Search
