Solve the problem.The table shows the population of a city over the past five years.
We used this data to develop the quadratic equation 
, which models the population of the city y in millions in the year x, where x = 0 represents 1995, x = 1 represents 1996, and so on. Use the model to find the estimated population in the year 1997.
