Dynamic Introduction to Function Monotonicity Definition

Dynamically illustrates the changing process of function increasing/decreasing behavior and the geometric meaning of the monotonicity definition. Core math concepts include function monotonicity, derivatives, and graph ascending/descending properties. Construction highlights the use of objects f, g, c and text labels a, b, text1, text2, text3 to build the dynamic graph and annotations. Suitable for high school or college introductory math classes to visually understand the definition of monotonicity.
