A company estimates that it will sell N(x) units of a product after spending x thousand dollars on advertising, as given by N(x) = -3x + 275x² – 3400x + 19000, 10 < x < 40. (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 'l' for o and '-l' for -o, and 'U' for the union symbol. If you have extra boxes, fill each in with an 'x'. N'(x) increasing: (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 x values of all inflection points of N(x). Note: If there are no inflection points, enter -1000. Average of inflection points = (D) Find the maximum rate of change of sales. Maximum rate of change of sales =
