Problem 1:

The height of water in a bathtub, w, is a function of time, t. Let P represent this function. Height

is measured in inches and time in minutes.

Match each statement in function notation with a description.

A: P (0)=0

1: After 20 minutes, the bathtub is empty.

B:P (4)= 10

2: The bathtub starts out with no water.

C:P (10) = 4

3: After 10 minutes, the height of the water is 4 inches.

D: P (20) = 0

4: The height of the water is 10 inches after 4 minutes.
