For which of the following would it be appropriate to use positive integers for the domain of the function? select all that apply. a) the function c(p) represents the cost for p people to attend the movies. b) the function m(t) represents the miles driven over t hours. c) the function t(m) represents the average high temperature for a given number of months. d) the function p(w) represents the profit of a farmer who sells whole watermelons. e) 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)
