A trigonometric function models the monthly rainfall of a city, which reaches a maximum monthly rainfall of 8 inches in the spring and fall and a minimum monthly rainfall of 0 inches in the summer and winter. If r⁡(t) models the monthly rainfall t months from when the monthly rainfall started being recorded for the city, what is the domain of function r?
