To determine on which interval the function is decreasing, you need to analyze the function's behavior over each of the provided intervals.
- Identify the function: You need either the function's graph, its equation, or a table of values to analyze its behavior.
- Check the intervals:
- For each interval provided (A: 40 to 44 seconds, B: 56 to 60 seconds, C: 64 to 66 seconds, D: 72 to 76 seconds), determine if the function's output is less than the output at the previous point within that interval.
Without additional information about the function (such as a graph or data points), it's not possible to definitively state which interval the function is decreasing on.
If you have the function or its values, please provide them, and I can help analyze it further!
