Answer:
![0\leq x \leq 10](https://tex.z-dn.net/?f=0%5Cleq%20x%20%5Cleq%2010)
Step-by-step explanation:
The function is
where x is the number of bottles of soda.
The domain means the set of "allowed" x values.
Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:
![f(x)=15-1.5x\\0=15-1.5x\\1.5x=15\\x=\frac{15}{1.50}\\x=10](https://tex.z-dn.net/?f=f%28x%29%3D15-1.5x%5C%5C0%3D15-1.5x%5C%5C1.5x%3D15%5C%5Cx%3D%5Cfrac%7B15%7D%7B1.50%7D%5C%5Cx%3D10)
This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>
![0\leq x \leq 10](https://tex.z-dn.net/?f=0%5Cleq%20x%20%5Cleq%2010)
