Describe the behavior of the function by determining over which interval the function has a negative average rate of change.

(1 point)
The average rate of change is negative over the interval [
,
].

Answer 1

I can't see the graph from your message. Could you either upload the image or paste the "Long Desc" text here?

If you want to find the interval yourself, here's how:
- The average rate of change on [a, b] is (f(b) − f(a)) / (b − a).
- That average is negative whenever f(b) < f(a) for b > a.
- So look for an interval [a, b] with b > a where the secant from x = a to x = b goes downward (right-hand value lower than left-hand value).

Send the graph or the long description and I will give the specific interval.
