Help anybody has an answered for this?

Answer 1

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.
