Interactive Logarithmic Function Parameter Demo

This GeoGebra applet demonstrates how varying parameters affect the logarithmic function graph. Users can adjust sliders for k (vertical scaling), a (base-related), h (horizontal shift), and c (vertical shift) to observe real-time transformations of f(x)=k·log(a(x-h))+c. The construction includes parameter sliders k, a, h, c, function f, text labels, and Y-axis. Ideal for high school mathematics teaching, helping students understand graphical transformations of logarithmic functions and the geometric meaning of parameters when base > 0 and base ≠ 1.
