Question

Lucy can buy up to 12 pencils at the store. The cost of the pencils is shown in the graph. What is the domain? A. All real numbers B. All whole numbers from 0 to 12 C. All rational numbers from 0 to 12 D. All nonnegative real numbers

Answer 1

The domain is the complete set of values of the independent variable.

Hence, the domain of this question as shown in the image starts from 0 to 12.

As 0 is the minimum number of pencil and the maximum is 12.

Hence, the correct option is all whole numbers from 0 to 12.
