Final answer:
None of the provided options are perfect for the viewing window of the function f(x) = x³ + 12 in the range of 0 to 20. However, Option D, is the closest to being correct, assuming an appropriate Xmax is chosen.
Step-by-step explanation:
To determine an appropriate viewing window for the function f(x) = x³ + 12 on a graphing calculator, we should consider the behavior of the function for a given range of x values. As the student has been asked to consider the function for 0 ≤ x ≤ 20, the cubic nature of the function means that the y-values will increase rapidly as x increases. Therefore, the y-values will start at 12 (when x=0) and be significantly higher at x = 20. Thus, we need a window that captures this increase adequately.
Reviewing each option and considering the function behavior:
- Option A: With Xmin=-12 and Xmax=12, the x-range is centered around the origin, which is unnecessary because we are considering 0 to 20. For y-values, Ymin=-10 and Ymax=10 will not capture the increasing y-values as x gets larger.
- Option B: The scale is symmetric around the origin, which is better for functions with symmetry or interesting behavior at negative x, neither of which applies here.
- Option C: Although Xmax=25 is slightly higher than necessary, it still allows us to view the function from 0 to 20, but Ymin=-5 and Ymax=5 are inadequate for the y-values we expect.
- Option D: Xmin=-6 and a missing Xmax, though Ymin=-6 and Ymax=25 would capture the y-values well. However, the incomplete information makes this option insufficient.
By assessing the behavior of f(x), none of the provided options are completely adequate; however, Option D comes closest if we assume an appropriate Xmax that's beyond 20. Given the incorrect options, we would ideally request a viewing window more like Xmin=0, Xmax=20, Ymin=12, and a Ymax that is comfortably greater than f(20), which is 812.
Therefore, the correct option is not listed, but Option D is the closest to being correct.
