Final answer:
The domain of 'x' is (2,4,7,-1) and the range of 'y' is (10,2,8,4).
Step-by-step explanation:
The domain of a function represents all the possible values of the independent variable. In this case, the independent variable is represented by 'x' and its domain is given as (2,4,7,-1). This means that the values of 'x' can only be 2, 4, 7, or -1.
Similarly, the range of a function represents all the possible values of the dependent variable. In this case, the dependent variable is represented by 'y' and its range is given as (10,2,8,4). This means that the values of 'y' can only be 10, 2, 8, or 4.
