Graphing Quantitative Relationships

Which of the following situations
corresponds to this graph? 

• 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.

Which point is on the graph?

• (0,0)

• (-2, -2)

• (0, 2)

• (2, 0)

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.

This graph shows the temperature in the lab for an entire experiment. (Determine which statement(s) is/are true.)

• The temperature reached its highest point during the experiment at Hour 12.

• The temperature was at its lowest when the experiment began.

• The temperature was decreasing for more hours than it was increasing during the experiment.

• The temperature at the end of the experiment was equal to the temperature at the beginning of the experiment.

Which is true about the function graphed?

True or False:
10 is in the domain of the function graphed.

• True

• False

True or False:
4 is a domain value in the function graphed.

• True

• False
