An advertising agency has found that when it promotes a new product in a city the weekly rate of change R of the number of people who are aware of the promotion follows a linear pattern. The weekly rate of change R of people who are aware of the promotion x weeks after it is introduced is described by the equation R = 1800-60x. Find the x- and R-intercepts and then graph the function on a viewing window that is meaningful in this application. What is the x-intercept? 30 (Type an integer or a fraction.) What is the R-intercept? 1800 (Type an integer or a fraction.) Choose the most appropriate viewing window boundaries for the function. OA. [0,60] by [1740,1800] OC. [0,1740] by [60,1800] OB. [-30,30] by [-1800, 1800] D. [0,30] by [0,1800] Choose the correct graph that uses the viewing window boundaries from above to show a complete graph of the function. Note: On the x-axis one tick mark=10 units and on the y-axis one tick mark=500 units. O A. Q Z O B. ✓ ○ C. E
