Solve the problem.Allied Radio is a company which makes clock radios. The following table gives the profit, y, in dollars that this company made during the three stated years, x.
This set of data can be modeled by f(x) = ax2 + bx + c, where x represents the year. Find a linear system for which the solution represents the values of a, b, and c. Use technology to solve this system. Then, using the quadratic equation, predict the profit that Allied Radio made in the year 1997. Round your answer to the nearest hundred dollars.
