Steve said that [5, 12) is the interval notation that represents the set of all real numbers greater than or equal to 5 and less than 12. Joe says that (5, 12] is correct interval notation. Who is correct and justify why?

Answer 1

Steve was correct in his statement.

Explanation:

According to standard notation, opening bracket (
`[` ) represents the lower bound of a set so that elements of the set are equal or greater than lower bound. In addition, closure parenthesis (
`)` ) represents the upper bound of a set so that element of the set are less than upper bound.

In consequence, Steve was correct in his statement.
