If f(x) is decreasing, then f'(x) is?
If a function f(x) is decreasing, it means that as the value of x increases, the value of f(x) decreases
If a function f(x) is decreasing, it means that as the value of x increases, the value of f(x) decreases. In other words, the slope of the function f(x) is negative.
The derivative of a function, denoted as f'(x), represents the rate of change of the function with respect to x. When f(x) is decreasing, it means that as x increases, the rate of change is negative, or the slope is negative.
Therefore, if f(x) is decreasing, f'(x) is negative.
