The domain is the set of all the possible values in the x-axis. In this case, the x-axis has the number of wrong questions and this number can be 0, 1, 2, 3, 4 or 5.
On the other hand, the range is the set of all the possible values in the y-axis and the y-axis contains the money that the contestant has left after x wrong questions. This number can be 250, 200, 150, 100, 50 or 0.
So, the domain is whole numbers from 0 to 5 and the range is multiples of 50 from 0 to 250.
