Final answer:
Based on the continuous function with hypercritical value = 2, the function is concave upward at x=2 and has an inflection point at x=2.
Step-by-step explanation:
Based on the given information that the hypercritical value is obtained from a continuous function, we can make the following conclusions:
- a. There is no local minimum at x=2, as it is not specified or implied by the information given.
- c. The function is concave upward at x=2, meaning it has a local maximum at x=2.
- d. The function has an inflection point at x=2, as it is concave upward at that point.
Therefore, options c and d are true based on the given information.
