Final answer:
b) Over the interval [-2, -1], the local minimum is 25. The local minimum of the graphed function occurs over the interval [-2, -1] and has a value of 25.
Step-by-step explanation:
The graphed function has a local minimum at a point where the function is at its lowest value in a small neighborhood. To determine the intervals where the local minimum occurs, we need to analyze the given options.
From the options, we can see that over the interval [-2, -1], the local minimum is 25. This means that the function reaches its lowest point within this interval. Therefore, the correct answer is option b).
