Here are descriptions of four situations in which the volume of water in a tank is a function of time. Match each description to a corresponding graph.

Draggable item		Corresponding Item
A 2,000-gallon water tank starts out empty. It is being filled for 5 hours, slowly at first, and faster later.		Graph A.
An empty 100-gallon water tank is filled in 50 minutes. Then, a dog jumps in and splashes around for 10 minutes, letting 7 gallons of water out. The tank is refilled afterwards.		Graph B.

Tyler filled up his bathtub, took a bath, and then drained the tub. The function gives the depth of the water, in inches, t minutes after Tyler began to fill the bathtub.

These statements describe how the water level in the tub was changing over time. Use the statements to sketch an approximate graph of function. We have talked about Tyler and his bath a lot in the last week. Now graph it out! Yes, there will be a couple of extimate moments, but the facts above should be evident.

Two functions are defined by these equations:

f(x)=5.1+0.8x

g(x)=3.4+1.2x

Which function has a greater value when x is 3.9? How much greater? Format like "h(x) is greater by 20.5" for instant grading.
