Understanding the Relationship between Increasing Derivatives and Curvature: Explaining the Connection between f'(x) and f”(x)

If f'(x) is increasing, then f”(x) is?

If the derivative of a function, f'(x), is increasing, it means that the rate at which the function is changing is itself increasing

If the derivative of a function, f'(x), is increasing, it means that the rate at which the function is changing is itself increasing. In other words, as x increases, the slope of the tangent line to the graph of f(x) is becoming steeper.

Now, the second derivative, f”(x), represents the rate at which the first derivative, f'(x), is changing. If f'(x) is increasing, it means that the slope of the tangent line to the graph of f(x) is increasing, which suggests that the graph is curving upward.

Therefore, if f'(x) is increasing, then f”(x) is positive or greater than zero. This indicates that the function is concave up, or in simpler terms, the graph of f(x) is curving upward.
