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)=113-4√x 9≤x≤289 How is p(x) related to f(x)? OA. The graph of p(x) is the graph of f(x) reflected in the x-axis, vertically stretched by 4, and shifted up 113 units. B. 1 and shifted down 113 units. The graph of p(x) is the graph of f(x) reflected in the x-axis, vertically shrunk by 4 OC. The graph of p(x) is the graph of f(x) vertically stretched by 4 and shifted up 113 units. OD. The graph of p(x) is the graph of f(x) vertically shrunk by 4 and shifted up 113 units. Find (A) f'(x). (B) the partition numbers for f', and (C) the critical numbers of f. f(x)=x³-27x-5 (A) f'(x) = (B) Find the partition numbers for f'. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The partition number(s) is/are x= (Use a comma to separate answers as needed.) B. There are no partition numbers. (C) Find the critical numbers for f. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The critical number(s) is/are x = (Use a comma to separate answers as needed.) OB. There are no critical numbers.
