Name______________________                                  FUNCTION INTERVALS  #2

PART A:  For each function below, place an x in the box that applies to each interval.    (8 points)

	

                                             					
Interval	Increasing	Decreasing	Neither	
-7 < x < -5				
-5 < x < -3				
-3 < x < 1				
1 < x < 7				
Interval	Increasing	Decreasing	Neither	
 -6 < x < -5				
-5 < x < -3				
-3 < x < 2				
2< x < 6				

PART B:  For each problem below, sketch a graph that matches the given intervals.    (12 points—Answer vary)

	

Interval	Increasing	Decreasing	Neither	
 -8 < x < -5	x			
-5 < x < -1			x	
-1 < x < 4	x			
4 < x < 8			x	

                                        					
Interval	Increasing	Decreasing	Neither	
-8 < x < -2		x		
-2< x < 2			x	
2 < x < 5		x		
5 < x < 8	x
