Company X tried selling widgets at various prices to see how much profit they would make. The following table shows the widget selling price, x, and the total profit earned
at that price, y. Write a quadratic regression equation for this set of data, rounding all
coefficients to the nearest hundredth. Using this equation, find the profit, to the
nearest dollar, for a selling price of 11.75 dollars.
