B. A linear model is a good fit for the data because the value of the correlation coefficient is close to −1.

C. A linear model is not a good fit for the data because the value of the correlation coefficient is negative.

For this case we have the following function:

c = f (b) = 10b

Where,

b: number of boxes

c = f (b): total cost

The domain of the function is:

b ∈ [0, ∞)

Where, the numbers belonging to the domain are whole numbers.

Therefore, the domain of the function are all natural numbers

The domain of the function is:

b ∈ ℕ
