Question:
<em>Note: It seems you forgot to add the complete question as the answer choices are missing. But, after a little research I am able to find the complete question. So, I am assuming that this was the complete question and I am answering based on this complete question which anyways would clear your concept. </em>
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 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.
Answer Explanation:
As we know that domain is the set of all possible input values x where the functions is defined.
So, following are the functions where it is suitable to use only positive integers for the domain.
<em />
<em>The function c(p) represents The cost for P people to attend the movies.</em>
It is appropriate to use positive integers for the function c(p) as it involves people and people can not be negative. Though total number of people can be zero.
<em>The function m(t) represents the miles driven over T hours</em>
It is appropriate to use positive integers for the function m(t) as it involves hours and hours can not be negative. Hours start with 1.
<em>The function t(m) represents the average high temperature for a given number of months.</em>
It is appropriate to use positive integers for the function t(m) as it involves the number of months and months can not be negative. Months start with 1.
<em>The function p(w) represents the prophet of a farmer who sells whole watermelons. </em>
It is appropriate to use positive integers for the function p(w) as it involves watermelon and watermelons can not be negative. The possible count of watermelon starts with 1.
<em>The function h(n) represents the number of person-hours it takes to assemble n engines in a factory.</em>
It is appropriate to use positive integers for the function h(n) as it involves number of engines and engines can not be negative. The possible count of engines starts with 1.
