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.

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 mouse population was the greatest around day 160.

• True

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

• False

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

Which statement about the relation is true?

• The relation is not function because is not continuous.

• The relation is a function because the x-values of the points are consecutives integers.

• The relation is a function because there is only one output for each input.

• The relation is not a function because both 0 and -3 are outputs for the input 1
