Interpreting Functions

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

• A)The bus is speeding up
•  B)The bus's speed is remaining constant
•  C)The Bus is stopped
•  D)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

What happened at point D going to E?

• the bus turned around

• the bus stopped

• the bus started moving again

• the bus slowed down

Describe the bus’s motion from B-C

• A)The bus is speeding up
•  B)The bus's speed is remaining constant
•  C)The Bus is stopped
•  D)The bus is beginning to slow down

Where is the object not moving?

• A

• B
