Solve the problem.The following points form a quadratic relationship: (1, 5.0), (2, 4.4), (3, 4.3), (4, 4.2), (5, 4.6), (6, 4.8), (7, 5.4), (8, 6.2) . The x-coordinates are the years a particular company has been in operation and the y-coordinates are the profit, in millions, for that year. Find the quadratic function that models the profit in millions as a function of x, the number of years of operation. Round to three decimal places.
