Using it's concept, it is found that the domain of the graphed function is given as follows:
D.
It is the set that contains all possible input values for the function. In a graph, it is given by the values of x.
In this graph, x assumes values between -4 and 2, inclusive due to the closed circle, hence the domain is given by:
