To solve this problem, I would need to examine the graphs of the function $f$ and its derivative $f'$ to find the average and instantaneous rates of change over the given interval. Unfortunately, the image you uploaded isn't viewable to me right now. Could you provide a description of the graph or key details from the graph, such as any significant points, slopes, or behavior of $f(x)$ and $f'(x)$?

Alternatively, if you prefer, you can upload a clearer or more detailed image.
