Exponential Functions - Derivative

This example demonstrates the tangent line and its slope at a point on the exponential function graph. Core math concepts include exponential functions, derivatives, tangent slope, and limits. It uses GeoGebra commands like Tangent, Slope, LaTeX, and objects such as sliders k, a, function f, point P, parameters b, m, and text elements text1, text2, text3, D. Suitable for high school mathematics to understand the instantaneous rate of change of exponential functions and the geometric meaning of derivatives.
