(b) The minimum on this interval is at #t = 0#, which corresponds to the first month of the model: November. The number of spoofs is about #color(red)4000#.

(c) The maximum on this interval is at #t = 11#, which corresponds to the last month of the model: October. The number of spoofs is about #color(blue)36000#.

(d) The rate of increase that is the greatest is wherever the function is the steepest. This appears to be during the 11th month. The rate of increase that is the smallest is wherever the function is the flattest. This appears to be during the 4th month.
