                             ANALYZING EQUATIONS  #1

PART A:  For each function below, fill in the missing inputs and outputs.    

1.		             2.     	              3.     	       4.  
Input (x)	Output (y)	
    4		
 	14	
Input (x)	Output (y)	
9		
	2

PART B:  Analyze the functions listed in each box.  The variable x represents the input and y is the output.  Circle all of the statements that apply to the function listed in the box. 
       								
a.  When the input is 2 the output is 14
                                                      
								b.  When the input is 3 the output is 18

y = 2x + 10

	5.  							c.  It’s graph is a straight line

								d.  The y-intercept is (0,2)

								e.  y is a function of x

a.  The y-intercept is (-2,0)
                                                      
								b.  The y-intercept is (0,-2)

y = -8x - 2

	6.  							c.  y is a linear function

								d.  When the input is -1 the output is 7

								e.  When the input is 1/2 the output is -6

a.  y is a not a function of x
                                                      
								b.  When the input is 15 the output is -8

	7.  							c.  When the input is 1 the output is -1

								d.  When the input is 6 the output is -7

								e.  The y-intercept is (1,-1)
