Use the Graph to Find the Intervals on Which It $( - 3 , - 1 )$

Use the graph to find the intervals on which it is increasing, decreasing, or constant.
-

A) Decreasing on $( - 3 , - 1 )$ and $( 1,4 )$ ; increasing on $( - 2,1 )$
B) Increasing on $( - 3 , - 2 )$ and $( 2,4 )$ ; decreasing on $( - 1,1 )$ ; constant on $( - 2 , - 1 )$ and $( 1,2 )$
C) Decreasing on $( - 3 , - 2 )$ and $( 2,4 )$ ; increasing on $( - 1,1 )$
D) Decreasing on $( - 3 , - 2 )$ and $( 2,4 )$ ; increasing on $( - 1,1 )$ ; constant on $( - 2 , - 1 )$ and $( 1,2 )$
