Projected t years from now a circulation of a magazine will be given C(t)=100t^2+400+500. Estimate the amount by which the circulation will increase during the next 6 months. Assume t=0 is the current year

I'm assuming you meant: C(t)=100t^2+400t+500. Anyway, 6 months is just t = .5, so plug in t = 0 and t = .5 and see what the difference is.
