For which of the following would it be appropriate to use positive integers for the domain of the function? 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 prophet of a farmer who sells whole watermelons. the function h(n) represents the number of person-hours it takes to assemble n engines in a factory

Domain is the x-values. 

Scenarios where positive integers are appropriately used for the domain of the function:

The function c(p) represents The cost for P people to attend the movies. (number of people can either be 0 going upwards)

the function m(t) represents the miles driven over T hours (hours always start with 1.)

the function t(m) represents the average high temperature for a given number of months (number of months always start with 1)

the function p(w) represents the prophet of a farmer who sells whole watermelons (count of whole watermelon starts with 1)

the function h(n) represents the number of person-hours it takes to assemble n engines in a factory (number of engines always start with 1)

The variables should add up to equal 1
