Describing Graphs of a Function

The graph shows how a motorboat travels around a lake. What does the graph most likely show?

• The boat travels at a constant speed for 10 minutes and then stops.

• The boat travels at a constant speed for 10 minutes and then slows down.

• The boat steadily increases its speed for 10 minutes and then stops.

• The boat steadily increases its speed for 10 minutes and then travels at a constant speed.

The value of a stock decreases sharply for 2 weeks, then increases sharply for 1 week,

and then decreases sharply again for 2 weeks.

Which graph shows the relationship between the value of the stock and time?
