Need help with this problem..

Need help with this problem...

If a population is changed by either immigration or emigration, a model for the population is 
dy/dt = Ky +f(t)      f(t) = -2t
where y is the population at time t and f(t) is some function of t that describes the net effect of the emigration/immigration. Assume that k = 0.02 and y(0) = 10,000. Solve this differential equation for y, given that

 

y = 100t + 5000 + 5000e-0.02t
 

y = 100t + 5000 + 5000e0.02t
 

y = -100t + 5000 + 5000e-0.02t
 

y = -100t - 5000 + 5000e0.02t
