(a) Find an exponential function of the form f(t) = y0b^t for these data, in which t = 0 corresponds to 2000 and f(t) is in millions.
(b) What is the projected population in 2040? In 2050?
(c) By experimenting with different values of t (or by using a graphing calculator to solve an appropriate equation), estimate the first full year in which the population will exceed 52 million.
