Continuity Condition Demonstration

This example demonstrates the continuity condition at a specific point a, visually showing the relationship between function values, left-hand and right-hand limits, and the function graph. It involves core mathematical concepts such as continuity definition, limits, exponential functions, interest calculation, translation, square operations, and multiplication. The construction uses GeoGebra commands like LaTeX, Point, and objects including f, a, b, text1, A, g, h, B, and multiple text objects (text2 series). Suitable for high school and above learners to understand the geometric meaning and computational applications of continuity and limits.
