When f ‘(x) is negative, f(x) is
decreasing
When f'(x) is negative, it means that the slope of the graph of the function f(x) is negative at that point. This means that the function is decreasing at that point.
Therefore, f(x) is decreasing at that point where f'(x) is negative. In other words, as x increases, the value of f(x) decreases.
