Answer 1

Answer: {1,2,3,4,5,6,7,8,9,10,11,12}

Explanation:

just took the test and this is the correct answer!

the person renting the boat could choose to rent it for any amount of hours up to 12, so we know that all of the numbers between 1-12 are practical for the domain.

Answer 2

Answer : [0,12]

The function ​f(x)​ is the cost of renting a boat where x represents the number of hours rented not to exceed 12 hours

Domain of the function is the x values that is the number of hours

x represents the number of hours rented not to exceed 12 hours

So the number of hours is between 0 to 12 hours

Hence the domain of the function f(x) is [0,12]
