A retail chain sells DVD players. The price-demand function of a particular model p(x) (in dollars) is given below for the weekly demand x. (A) Describe how the graph of function p can be obtained from the graph of f(x)=x. (B) Sketch a graph of function p. p(x)=117-3x 9x289 How is p(x) related to f(x)? OA. 1 The graph of p(x) is the graph of f(x) reflected in the x-axis, vertically shrunk by and shifted down 117 units. 3 B. The graph of p(x) is the graph of f(x) reflected in the x-axis, vertically stretched by 3, and shifted up 117 units. C. The graph of p(x) is the graph of f(x) vertically stretched by 3 and shifted up 117 units. . The graph of p(x) is the graph of f(x) vertically shrunk by 3 and shifted up 117 units. Choose the correct graph of p(x). O A. Ap(x) 120- 200 E O B. C. Ap(x) a Ap(x) O D. Ap(x) 200- Q 120- 200- 200 G 200 G 220
