Solve the problem.Several years ago, a large city undertook a major effort to encourage carpooling in order to reduce traffic congestion. The accompanying table shows the number of carpoolers, in thousands, from 1995 to 2000. Use regression to obtain a function  that models the data, where  corresponds to 1995,  to 1996, and so on. Round the constants a and b to the nearest hundredth.
