Answer: The domain of a graph is the set of all the possible input values (x-values) for which the function is defined. The domain is the set of all x-values that can be plugged into the function without resulting in an error or undefined value.
Without a function to graph, it is impossible to determine the domain. The options you provided refers to different inequalities that could represent the domain but without a function it is impossible to know which one is correct.
