Answer:
Domain = (-∞, 0]
Explanation:
The domain of a function is the set of all possible input values (x-values) for which the function is defined.
The graphed function has a closed circle endpoint at the origin (0, 0) and continues infinitely to the left (as x approaches -∞).
A closed circle indicates that the endpoint is included in the domain. So, the origin (0, 0) is included in the domain.
Therefore, the domain of the function consists of all real numbers less than or equal to 0, which is represented in interval notation as (-∞, 0].
