Which of the following situations
corresponds to this graph?

• A car, accelerates from a stop,travels at a constant speed, slows,
  and then travels at a slower speed.
• An airplane travels at a constant
  speed then decelerates to a slower speed.
• An athlete warms up by walking
  around the track, runs, then jogs.
• A bicyclist accelerates, travels at a
  constant speed, then slows to a
  stop.

• A bicyclist accelerates from a stop, travels at a constant speed, then slows to a stop.
• A car accelerates from a stop,
  travels at a constant speed, slows,
  and then travels at a slower speed.

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
