Solve the problem.
= ky + f(t) is a population model where y is the population at time t and f(t) is some function to describe the net effect on the population. Assume k = .02 and y = 10,000 when t = 0. Solve the differential equation of y when f(t) = -21t.
A. y = -1050t - 52,500 - 42,500e.02t B. y = 1050t + 52,500 - 42,500e-.02t C. y = -1050t + 52,500 - 42,500e-.02t D. y = 1050t + 52,500 - 42,500e.02t
