A bacterial culture is growing according to the logistic growth function y = 1.25 /(1 + 0.25e−0.4t)() , t ≥ 0 where y is the weight of the culture in grams and t is the time in hours. Find the weight of the culture after (a) 0 hours, (b) 1 hour, and (c) 10 hours. (d) What is the limit as t approaches infinity?
