A store sells self-serve frozen yogurt sundaes the function C(w) represents the cost, in dollars, of a sundae weighing w ounces. An appropriate domain for the function would beA. IntegersB. Rational numbersC. nonnegative integers D. nonnegative rational numbers

The domain would be ur w values....the weight in ounces. So the weight would have to be positive numbers because it is not gonna weigh negative. And it would not necessarily have to be a whole number...because the sundae could weight 2.5 oz......so ur answer is : non-negative rational number
