Guided Practice

In a lab environment, colonies of bacteria follow a predictable pattern of growth. The graph shows this growth over time.

The graphs give the speeds of three people who are riding snowmobiles. Tell which graph corresponds to each situation.

Question 3 (request help)
Chip begins his ride slowly but then stops to talk with some friends. After a few minutes, he continues his ride, gradually increasing his speed.

Question 4 (request help)
Linda steadily increases her speed through most of her ride. Then she slows down as she nears some trees.

Finally, he swam forward and upward to the surface of the water. Draw a graph to represent Paulo’s elevation at different distances from the edge of the pool.
