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(p) represents the cost for (p) people to attend the movies. The function m(t) represents the miles driven over t hours. The function t(m) represents the average high temperature for a given number of months. The function p(w) represents the profit of a farmer who sells (w) whole watermelons. The function h(n) represents the number of person-hours it takes to assemble (n) engines in a factory.
The functions in which it would be appropriate to use only positive integers for the domain are:
1. c(p) - The cost of attending the movies should only be considered for a positive number of people. It does not make sense to have a negative or zero number of people attending the movies.
2. m(t) - The miles driven over a certain number of hours should also have a positive number of hours. It does not make sense to have a negative or zero number of hours.
4. p(w) - The profit of a farmer who sells whole watermelons should only be considered for a positive number of watermelons. It does not make sense to have a negative or zero number of watermelons.
5. h(n) - The number of person-hours it takes to assemble engines in a factory should only be considered for a positive number of engines. It does not make sense to have a negative or zero number of engines.
