2.

A cylindrical tank, shown in the figure above, is partially full of water at timet = 0, when more water begins flowing in at a constant rate. The tank becomes halffull when t = 4, and is completely full when t = 12. Let h represent the height of the water at time t. During which interval is increasing?
