To determine the intervals where the function has a negative average rate of change, we need to look for segments where the function decreases.
Given the described behavior of the function:
- It starts at 0, goes up to 1 (increasing).
- Then it goes up to 2 (increasing).
- It then goes down to 3 (decreasing).
- Next, it goes back up to 4 (increasing).
- Finally, it goes up to 5 (increasing).
The only interval where the function decreases (and thus has a negative average rate of change) is when it goes from 2 to 3.
Thus, the interval with a negative average rate of change is: [2, 3].
