Name______________________                        FUNCTION INTERVALS  #2—RUBRIC

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

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
