A compound inequality contains at least two inequalities that
are separated by either "and" or "or".
The graph of a compound inequality with an "and" represents the
intersection of the graph of the inequalities. A number is a
solution to the compound inequality if the number is a solution to
both inequalities. It can either be written as x > -1 and x <
2 or as -1 < x < 2.
The graph of a compound inequality with an "or" represents the
union of the graphs of the inequalities. A number is a solution to
the compound inequality if the number is a solution to at least one
of the inequalities. It is written as x < -1 or x > 2
