Answer: F has a local minimum at x=0, the local minimum is -2
Explanation:
We use the graph to determine the local maximum and local minimums but since we're just looking for the local minimum we use the lowest part of the function on the graph. We see the lowest part on the line at the bottom hump which is x=0. Since we only see one we can assume the lowest to be that point which also sits at y = -2 so the answer is D
