Question

1. Construct a table of values for the equation y= x/2 if the replacement set is {-4, 0, 2}. 

2. Given the equation y=1/2lxl
a. Construct a table of values for the solution set. Be sure to include at least two negative values, two positives values, and zero.

Answer 1

1) Construct a table for the equation y = x/2 of values -4, 0 ,2

 

x	y = x/2
–4	–2
0	0
2	1

 

2) Construct a table for the equation y=1/2lxl  of values  -2 ,-1, 0 ,1 and 2

x	y=1/2lxl
–2	1/4
–1	1/2
0	∞
1	1/2
2	1/4
