Consider this scenario: The profit of a company decreased steadily over a ten-year span. The profit depends on the number of units sold. The following ordered pairs show the number of units sold x in hundreds and the profit P in thousands of dollars over the ten-year span in the form (x, P(x)) for specific recorded years. (46, 1580), (48, 1530), (50, 1485), (52, 1520), (54, 1475) Use linear regression to determine a function P(x). (Round the coefficients to three decimal places.)
