-
Maximum Values of and :
- From the graph, the maximum value of is .
- The maximum value of is computed as follows:
- is a cubic function. To find its maximum, we differentiate and solve : The critical points are and .
- Evaluating at : Thus, has a maximum value of , which is higher than the maximum value of .
-
Comparison of End Behavior:
- For , as , , as this is a downward-opening polynomial.
- For , as , , because the cubic term dominates.
Correct Answer for End Behavior:
- The correct answer is C: "For both functions, when , ."
