Interpreting Function 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

Match the following

This graph shows the population of mice in a study, modeled as a function of time.  The study begins on day 0 and ends on day 200.  Select True or False for each statement.

• True

• There are two intervals of time where the mouse population decreases.

• True

• The least number of mice during the study was 130.

• False

• The mouse population was decreased between day 40 and day 80.

• True

• The mouse population was the greatest around day 160.

A bird flies out of its nest.  This graph represents the distance it flies from its nest (in meters) as a function of time (in seconds).

Place a X to mark the point on the graph that represents the bird’s greatest distance from its nest.

Place a O to mark the point that represents the bird’s return to its nest.
