Answer choice
C) All nonnegative real numbers

D) All positive integers

The number of boxes can't be negative or in fractions.

so the domain would be "All whole numbers from 0 to 10"

A) All whole numbers from 0 to 10.

Step-by-step explanation:

The domain of a function is given by the available values of the independent variable.

In this case you have that the independent variable is the number of boxes, and the available values of this variable are integers in between 0 and 10, by including 0 and 10.

Then, the domain of the functions composed by all positive integers number from 0 to 10 including 0 and 10.

A) All whole numbers from 0 to 10.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
