A function is created to represent the costs of living per person in the family. What restrictions would be made to the domain?
Nitella [24]

Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.
