Consider a machine that exchange quarters for dollar bills. Inserting one dollar bill returns four quarters and you may insert up to five one dollar bills at a time. Is 7 a possible input for the relation this change machine represents ?

No because it says you can only insert up to 5 Dollar Bills unless you put them in one at a time.
