Understanding Increasing f'(x) and its Implications on the Graph of f(x): Exploring the Connection between Derivatives and Curvature

When f ‘(x) is increasing, f(x) is

When f ‘(x) is increasing, it means that the derivative of f(x), denoted as f ‘(x), is increasing

When f ‘(x) is increasing, it means that the derivative of f(x), denoted as f ‘(x), is increasing.

In simple terms, it means that as x increases, the slope of the graph of f(x) is increasing. This can be represented graphically by the slope of the tangent line to the graph of f(x) getting steeper and steeper as x increases.

So, if f ‘(x) is increasing, it tells us that the rate at which f(x) is changing is increasing as x increases. In other words, the function f(x) is getting steeper or becoming more “curvy” as x increases.

To understand this concept further, let’s consider an example:

Let f(x) = x^2 be a function. The derivative of f(x) is f ‘(x) = 2x.

If we graph f(x) = x^2, we see that the slope of the tangent line increases as x increases. This implies that the rate of change of f(x) is increasing.

For instance, at x = 1, the slope of the tangent line is 2. As x increases to 2, the slope of the tangent line becomes 4, which is greater than 2. Similarly, as x increases further, the slope of the tangent line continues to increase.

Therefore, when f ‘(x) is increasing, it indicates that the function f(x) is becoming steeper or more “curvy” as x increases.
