where the "?"s are, is either "(" or "[".
.
First, it should be abundantly obvious that .
To solve this inequality for , you will need to consider two cases, the first being when is positive, and the second when is negative, since multiplying/dividing by a negative reverses the inequality sign.
Case 1: .
.
Since and , putting it together gives , or .
Case 2:
.
So and . Putting it together gives , or .
Therefore, our final solution is
. You can check this by graphing the functions and and making sure that everything below the line are the values listed above.
