Analyzing Functions and Graphs

 Every morning, Tom walks along a straight road from his home to the bus stop. Below, is a graph representing Tom’s trip to school.
- What is the distance covered through the second segment, which is between 50 seconds, and 70 seconds?

• 60 meters

• 80 meters

• 20 meters

Increases at an increasing rate.

• E

• A

• F

• C

Describe the situation.

• Sales decrease quickly at a constant rate, and then increase slowly at a constant rate.

• Sales stay constant, then decrease at a constant rate, and increase slowly.
