Abs value derivative - 5. Can derivatives of ABS values be negative? Yes, derivatives of ABS values can be negative. This indicates that the function is decreasing at that particular point. However, the absolute value of the derivative will always be positive, as it represents the rate of change of the absolute value of the function.
