Solve the problem.Southern Granite and Marble sells granite and marble by the square yard. One of its granite patterns is price sensitive. If the price is too low, customers perceive that it has less quality. If the price is too high, customers perceive that it is overpriced. The company conducted a pricing test with potential customers. The following data was collected. Let f(p) be the number of buyers of the granite pattern at price p. Use a graphing calculator to plot the data. Find and verify an equation of f.
A. f(p) = -0.243p2 + 3.115p - 22.13 B. f(p) = -0.0243p2 + 3.115p - 22.13 C. f(p) = 0.0243p2 - 3.115p - 22.13 D. f(p) = -0.0243p2 + 3.115p + 22.13
