Solve the problem.dy/dt = 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 
when t = 0. Solve the differential equation of y when f(t) = 9t.
A. y = -450t - 22,500 + 32,500e-.02t B. y = 450t - 22,500 + 32,500e-.02t C. y = 450t + 22,500 + 32,500e-.02t D. y = -450t - 22,500 + 32,500e.02t
