It is aimed at beginners, as part of a larger unit on the concepts of domain and range in functions. Learners are provided with graphical representations of functions, and they must determine whether the domain comprises all possible X values or Y values. There are multiple questions designed to reinforce the definition and identification of domains in different function representations.
