The finances of a group of pet owners were analyzed to determine how much they were spending on their pet(s) each year. A graph of that data is shown: A graph with Number of Owners on the x axis and Yearly Cost of Pets, in hundreds, on the y axis. The x axis has a scale from 1 to 10 with an increment of 1. The y axis has a scale of 5 to 15 with increments of 1. A curved line connecting 1, 15, approx 3, 7, and 10, 0 is drawn.

Would (2.5, 8.5) be a realistic solution for the function? Explain.

Yes, it is realistic to have 2.5 owners.
No, it is not realistic to have 2.5 owners.
Yes, it is realistic that owners spend $850 a year on their pet(s).
No, it is not realistic that owners spend $850 a year on their pet(s).
