7:28 PM ì webwork.uoregon.edu o AT&T令 (1 point) A company estimates that it will sell N(z) units of a product after spending z thousand dollars on advertising, as given by N(z) =-3x3 + 250m2-3000z 19000, 10 40. z (A) Use interval notation to indicate when the rate of change of sales N'(x is increasing. Note: When using interval notation in WeBWorK, remember that: You use ' for oo and - for-o, and 'U' for the union symbol. If you have extra boxes, fill each in with an N(x) increasing: (6.842,inf) (B) Use interval notation to indicate when the rate of change of sales N(x) is decreasing. N (x) decreasing (C) Find the average of the values of all inflection points of N(x) Note: If there are no inflection points, enter -1000. Average of inflection points- 16 (D) Find the maximum rate of change of sales. Maximum rate of change of sales- 840
