Solve and graph:
, D=(Integers)
Add -2 to both sides
Multiply both sides by
, which
reverses the inequality:
You need the rule that to remove the absolute value
bars from
, where A is a
POSITIVE number, you replace it by this three-sided
inequality:
Using that rule,
becomes
Putting that on a graph (number line):
Since you are only using the integers for the
domain D, put a black dot at each of those
numbers between -2 and 2
