I don’t have the graph image content here. Could you either upload the image or paste the “long description” (the coordinates or key points of f at x = 0,1,2,3,… and any curve segments)?

If you’d rather do it yourself, check this quick method and tell me the endpoint values:

- For each interval [a,b] compute the average rate = (f(b) − f(a)) / (b − a).
- If f(b) − f(a) < 0 the average rate is negative on that interval.

Give me the values f(0), f(1), f(2), f(3), f(4), f(6), f(7) (or the long description) and I’ll pick the correct response.
