The meteorologist reports that it will melt at a rate of 1.5 inches per day for 8 days. Then frigid temperatures over 3 days will prevent the snow from melting. However, starting on Day 11, steady snow will fall for the next 5 days, but only 7 of an inch will accumulate per day. Let d represent the time in days since Thursday, and let h represent the height of the snow. @ Graph the function for the height of the snow over time. 20 16 Height of the Snow (inches) 12 00 4 8 12 16 20 * Time (days) Describe each interval of increase, interval of decrease, or constant interval.
