Answer:

Steve was correct in his statement.

Step-by-step explanation:

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