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 2007 to 2012. Use regression to obtain a function that models the data, where
corresponds to 2007,
to 2008, and so on. Round the constants a and b to the nearest hundredth.
