When f ‘(x) is negative, it means that the derivative of the function f(x) at the given point x is negative
When f ‘(x) is negative, it means that the derivative of the function f(x) at the given point x is negative. This provides information about the behavior and slope of the function at that specific point.
To better understand what happens to f(x) when f ‘(x) is negative, we need to recall the definition of the derivative. The derivative of a function f(x) represents its rate of change or instantaneous slope at a given point. When the derivative is negative, it indicates that the function is decreasing at that point.
In other words, if f ‘(x) is negative at a specific x-value, it means that as we move from left to right along the x-axis, the function f(x) is decreasing in value. Graphically, this would be represented by a decreasing slope or a downward trend on the graph of f(x).
It is important to note that the negativity of f ‘(x) only provides information about the behavior of the function at a specific point, not the overall behavior of the function. For a complete understanding of the function’s behavior, it is necessary to analyze the signs of f ‘(x) across its entire domain.
