The water level in Phoenix lake varies during the year. Let h(t) be the depth in feet of the water at time t days. So, January 1 would correspond to 0 ≤ t < 1. Match each description on the left with the mathematical expression on the right. Not every mathematical expression will be used. The water level is rising and the rise is going faster and faster at time a. The water level is falling at time t = a. The water level is constant at 50 feet on January 2nd. On January 2nd, the water rose steadily at 50 feet per day. The water level is rising at time t = a.
