Answer 2

Answer:

The option is: all integers from 1 to 5 inclusive

Step-by-step explanation:

The domain of a function is the set of all values ​​for which the function is defined, we have this information about the domain:

1. Susan cannot purchase partial bags (so the domain are integers, dont accept real numbers)

2. She can purchase up to 5 bags of flour (the domain is limited from 1 to 5)

With this information we can conclude that the only available option is the second: She can purchase up to 5 bags of flour
