Picture a set of ordered pairs. i.e: (-3,3), (-4,4), (-5,5), (-6,6), (-7,7). The first number, or the "x", is the Input, and the second number, or the "y", is the Output. Therefore, your domain would be {x | -3 < x < -7}. (-3) is the smallest "x" value, and (-7) is the largest "x" value. The term {x | -3< x< -7) is your domain.
In the same set of ordered pairs, (-3,3), (-4,4), (-5,5), (-6,6), (-7,7), the second number, or "y" value, is your ouput. You use these to find the Range. I.e: {y | 3 < y < 7}. The 3 is the smallest y value and the 7 is the largest. The "<"s are saying that 3 is less than or equal to "y" and "y" is less than or equal to 7. The term {y | 3 < y < 7} is your Range.
