Answer 1

Answer:

An alternative form of expressing inequalities is to use interval notation. Interval notation consists of two values, separated by commas.

• The first value is the left hand endpoint of the interval, and the second value is the right hand endpoint of the interval. The left hand endpoint is always on the left, and the right hand endpoint is always on the right. If the inequality extends forever in the negative direction, then the left hand endpoint should be negative infinity. If the inequality extends forever in the positive direction, then the right hand endpoint should be positive infinity.

• Each endpoint is surrounded by either a bracket [ ] or parenthesis ( ). The left hand endpoint is proceeded by a left bracket [ or left parenthesis ( and the right hand endpoint is followed by a right bracket ] or right parenthesis ). A bracket means the endpoint is included and a parenthesis means the endpoint is not included.
• Infinity (positive or negative) is never included and should always be enclosed with a parenthesis.
