Answer:
The correct option is the third: All positive real numbers
Step-by-step explanation:
The domain of this function are all possible values that x can take. If we are talking about the number of miles traveled, these can be as many as the client travels (20.5, 670.23, etc), or zero, if not traveled any. But x can never be less than zero, since it would be absurd for a customer to have traveled -20 miles, for example. Therefore x can take any positive value. The domain of the function is
x> 0
The correct option is the third: All positive real numbers
Answer:
Concept: Application of Real world problems
- They counted 470470470 milliliters
- You donate on average 470 ml per person
- So 470470470÷ 470= 1,001,001 people.
Answer:
to graph an inequality you need a variable. your question does not have a variable. please rewrite the question.
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.
