EXPLANATION:

We are given the set of real numbers in interval notation as follows;

[tex](-\infty,-1][/tex]

We are required to identify the numbers that belong in this interval.

Note that the left side has a parenthesis, while the right side has a bracket.

The parenthesis means the number is excluded from the set, while the bracket indicates that the number is included in the set.
