Answer:

If f′(x)<0 on an open interval, then f is decreasing on the interval.

Step-by-step explanation:

f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I. Because the derivative is zero or does not exist only at critical points of the function, it must be positive or negative at all other points where the function exists.
