A variable solution for the function is not realistic to have 4.5 owners.
In the given graph x-axis represents the number of owners and the y-axis represents the yearly cost of pets, in hundreds.
It is given that the graph passes through the points (1,15), (3,7), and (10,0).
We need to check whether (4.5, 6) is a realistic solution for the function or not. (4.5,6) point represents
<h3>
What is a realistic solution?</h3>
1 showing awareness and acceptance of reality. 2 practical or pragmatic rather than ideal or moral. 3 (of a book, film, etc.) depicting or emphasizing what is real and actual rather than abstract or ideal.
Number of owners = 4.5
the yearly cost of pets = 6
It is realistic that owners spend $600 a year on their pet(s).
A number of owners can not be a fraction value. So, it is not realistic to have 4.5 owners.
Therefore, the correct option is D.
