Functions of Graphs

The number line above tracks where a function's y-value is positive or negative. Which of the following could be the equation of the function represented above?

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

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

Where is the object not moving?

• A

• B

• C

• E

What happened during E to F point?

• not moving

• moving at a constant rate

• moving faster than before
