Final answer:
Fatima should shade 1 large group consisting of x^3 small squares, where each small square represents 0.09, making the correct answer B) 1, 9, x^3.
Explanation:
When Fatima is shading a model to show 0.09x^3, she should shade 1 group of x^3 small squares, with each small square representing 0.09 of a unit. Therefore, the correct answer is B) 1, 9, x^3. This means she shades 1 large group of x^3 small squares, and each small square is 1/9 of the large group, representing the decimal 0.09.
