Use a graphing calculator to plot the data and find the quadratic function of best fit.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. Use a graphing calculator to plot the data. What is the quadratic function of best fit?
A. B(x) = -0.0243x2 + 3.115x + 22.13
B. B(x) = -0.243x2 + 3.115x - 22.13
C. B(x) = -0.0243x2 + 3.115x - 22.13
D. B(x) = 0.0243x2 - 3.115x - 22.13
