When f ‘(x) is positive, it means that the derivative of the function f(x) with respect to x is positive at that particular value of x.
The derivative is a mathematical tool that measures the rate of change of a function. In this case, when f ‘(x) is positive, it indicates that the function f(x) is increasing at that specific value of x.
To understand this concept better, let’s consider an example. Suppose we have a function f(x) = 2x. The derivative of this function is f ‘(x) = 2. Here, the derivative is a constant which is positive. This means that for every value of x, the function f(x) is increasing at a constant rate of 2.
In general, if f ‘(x) is positive, it implies that the function f(x) is ascending, or moving upwards. As x increases, the function value f(x) also increases.
It is important to note that f(x) could still have intervals where it is decreasing or stays constant, but as long as f ‘(x) is positive, overall, the function is trending upward.
