C. All whole numbers from 0 to 10

Step-by-step explanation:

Options:

A. All nonnegative real numbers

B. All rational from 0 to 10

C. All whole numbers from 0 to 10

D. All real numbers

Given:

A student can not buy more than 10 books.

The domain is the x-axis which is the number of books.

You can not buy half or a fourth of a book.

Nonnegative real numbers  would include 0.1, 0.2, 0.3, 0.4, 1.5, etc.

Rational numbers from 0 to 10  would include integers, fractions, and repeating decimals which include 1/3, 2/4, 3/4, 6/5, etc.

Whole numbers from 0 to 10 would include integers and a rational.

Real numbers include negative number, but the students are not selling books.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
