look at the first entry in the table
if x = - 4, y = 4
now look at each rule
1st rule says,
that y = -x ( y equals the neg of x)
2nd rule says,
y = -4 (the value for y is -4)
3rd rule says
y = 2x (y is two times the value of x)
y = x (y and x are the same)
since if x = - 4, y = 4 (1st entry)
the rule would be
y = -x
do you understand?
look at the other entries in the table and see how they all follow this rule
