Focus K: Absolute-Value and Inequalities

1. x = 3
2. Essentially, any number between -3 and 3 will satisfy the inequality. In other words, x < 3 and  x > -3. This can also be written in compact form,
    -3 < x < 3.
3. Any number greater than 3 or less than -3 will satisfy the inequality.
    i.e., x > -3 or x < -3. 

Note the specific usage of the words "and" and "or." The word "and " is used when the interval is between two values.
