X-min = X-max = (b) If P-min = 0, use a table to determine the smallest value for P-max that would show a complete graph of the model. 20 O 40 O 60 O 80 100 (c) Graph this equation. 30 80 60 40 40 20 20 - X 20 40 60 80 100 120 20 40 60 80 100 120 P P esc F1 F2 380 F4 F5 - F6 4 F7 F9 @ A LA N 6 8 O Q W E R T Y U O P A S D F G H K Z X C V B N M altContent * VA PreCB homework 1.4 - Ma164 | x G Graph the function using a win x Search Results | Course Hero x + -> C webassign.net/web/Student/Assignment-Responses/last?dep=26733445 5. [-/2 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An advertising agency has found that when it promotes a new product in a city of 350,000 people, the rate of change R of the number of people who are aware of the product is related to the number of people x who are aware of it and is given by R = 28,000 - 0.08x where x 2 0 and R 2 0. (a) Use the intercepts to determine a window, and then graph the equation for x 2 0. 50 000 25 000 40 000 20 000 30 000 15 000 20 000 10 000 10 000 5000 X L X 100 000 200 000 300 000 400 000 100 000 200000 300 000 4 400 000 50 000 25 000 40 000 20 000 30 000 15 000 20 000 10 00 10 000 5000 X O 100 000 200 000 300 000 400 000 0 100 000 200 000 300 000 400 000 (b) Is the rate of change increasing or decreasing?
