Functions and Interpreting Graphs

What is happening in the graph between 30 and 40 minutes?

• Sarah is accelerating

• Sarah is not moving

• Sarah is slowing down

• Sarah is travelling at a constant speed

What is happening in this graph from point A to B? HINT: Look at the axis labels.

• The object is accelerating.

• The object is not moving.

• The object is decelerating.

• The object is moving at a constant speed.

What is happening at D?

• Stationary

• Accelerating

• Fast steady speed; moving away from the starting position

• Slower steady speed; moving away from the starting position

What is happening at A?

• Stationary

• Accelerating

• Slower steady speed; moving away from the starting position

• Steady speed; returning to start position

Where is the object not moving

• A-B

• O-A

• C-D

• B-C

Describe the bus’s motion from A-B

• The bus is speeding up

• The bus's speed is remaining constant

• The Bus is stopped

• The bus is beginning to slow down

Describe the bus’s motion from C-D

• The bus is speeding up

• The bus's speed is remaining constant

• The Bus is stopped

• The bus is beginning to slow down

Describe the bus’s motion from B-C

• The bus is speeding up

• The bus's speed is remaining constant

• The Bus is stopped

• The bus is beginning to slow down

Where is the object not moving?

• A

• B

• C

• E
