The rate at which an animal population is changing is given by r(t) = 30 cost animals per month, where t represents time, in months, after January 1st. In other words, t = 0 represents the beginning of January. (a) Is the animal population increasing or decreasing at the beginning of February? At what rate? Clearly answer both questions, and include appropriate units. (b) At the beginning of April, is the population greater or less than it was at the beginning of February? How much greater or less? Clearly answer both questions, and include appropriate units.
