Find the range of values of for which
So you want to find x so that or
If |x|> 2, then so those are the same as
and
which are, of course, the same as
and
What values of x> 2 or x< -2 satisfy those?
If |x|< 2 then so those are the same as
and
which are the same as
and
What values of x, -2< x< 2, satisfy those?
