In which of the following functions would it be appropriate to use only positive integers for the domain? Select all that apply.

The function c (x) represents the cost for (x) people to attend the movies.

The function m (n) represents the predicted amount of bracelets sold as the price (n) changes.

The function t (q) represents the temperature of water at (q) distance below sea level.

The function p (w) represents the profit of a farmer who sells (w) whole watermelons.

The function h (p) represents the number of person-hours it takes to assemble (p) engines in a factory.

The function c (x) represents the cost for (x) people to attend the movies. The function p (w) represents the profit of a farmer who sells (w) whole watermelons. The function h (p) represents the number of person-hours it takes to assemble (p) engines in a factory

Step-by-step explanation:

People, watermelons, and engines are countable objects, so best represented by positive integers.

Price and distance (elevation) are not restricted to integer values, though we sometimes round them to integer values. Certainly, distance below sea level is usually represented by a negative (not positive) number.
