Name______________________                                FUNCTION INTERVALS  #1

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

	

                                             					
Interval	Increasing	Decreasing	Neither	
-8 < x < -6				
-6 < x < -4				
-4 < x < 1				
1 < x < 6				
Interval	Increasing	Decreasing	Neither	
 -7 < x < -5				
-5 < x < -2				
-2 < x < 3				
3< x < 4				

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 < 0		x		
0 < 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
