To determine the intervals where the function \( f \) is decreasing, we need information about its derivative \( f' \). Generally, a function is decreasing on intervals where its derivative is negative.
However, since the specific function and its derivative are not provided, I cannot directly assess the correct intervals. If you have a graph or a table of values for the function or its derivative, you could look for where the slope (derivative) is negative.
Here’s how you can do this:
- Find the derivative \( f'(x) \).
- Determine where \( f'(x) < 0 \).
- Identify the corresponding intervals.
If you provide the necessary information about the function or its derivative, I can help you determine the intervals where the function is decreasing. Otherwise, based on common intervals, the potential options would be:
- (5, ∞)
- (0, 5)
- (−∞, 4)
- (-5, 0)
- (4, -5)
Please clarify or provide additional details.
