1
Q

A
A solution set
2
Q
What are three methods of writing solution sets for simple inequalities?
A
1) a form of set notation
2) a number line graph
3) interval notation
3
Q
What is interval notation?
A
A symbolic way of indicating a selected interval of the real number line.
4
Q
What is the format of interval notation?
A
When a number acts as the boundary point for an interval (also called an endpoint), we use a left bracket “[” or a right bracket “]” to indicate inclusion of the endpoint.
When a boundary point is not included, we use a right parenthesis “(“ or left parenthesis “(“
