Cool Down

A squirrel runs up and down a tree.

The graph shows the height of the squirrel, hh (feet), as a function of time, tt (seconds).

A line graph shows height in feet vs. time in seconds. Height rises to 14 feet at about 1.5 sec, drops to 0 at 4 sec, then quickly rises to 10 feet and levels off from 6 to 8 sec.
1.

What is the highest point the squirrel reaches?

Compare your answer:

14 feet

2.

Solve h(t)=0h(t)=0. What does this solution tell you about the squirrel?

Compare your answer:

t=4t=4 means that after 4 seconds, the squirrel is at the bottom of the tree on the ground.

3.

Find the vertical intercept of the graph. What does it tell you about the squirrel?

Compare your answer:

(0,9)(0,9) means that at the beginning, the squirrel is 9 feet high in the tree.
