see explanation.

#### Explanation:

$x < - 3 \text{ is a solution to an inequality}$

This means that all values of x must be less than - 3 but not equal to - 3.
In interval notation this is denoted by using (

If x could equal - 3 then it is denoted by using [

$x < - 3 \text{ in interval notation is } \left(- \infty , - 3\right)$
