Domain: Set of all nonnegative integers (ie integers that are not negative)

Range: The set {0, 1200, 2400, 3600, 4800, ...}


The reason why negative numbers are excluded is because negative bag counts or negative area doesn't make much sense. Integers are stressed here because you cannot buy half a bag (you must buy whole bags)

The range is simply the set of all multiples of 1200
