Answer:
Step-by-step explanation:
The correct domain consists of only five integers: {0, 1, 2, 3, 4} It's possible that the customer buys NO melons; that's why we have that 0 in the domain. No customer may buy more than 4 melons; that's why the domain does not include numbers greater than 4. Only whole melons are sold, which is why the domain contains no fractions, no mixed numbers.
