Exponents of 2: Positive, Negative, Zero

This example demonstrates the graphical representation and variation patterns of positive, negative, and zero exponents of 2. The core mathematical concepts involved include exponent operations, function graphs, and sequence changes. The construction utilizes GeoGebra commands like Text for displaying text and objects such as f, X, Y, text1, text2, text3, text2_1, text4, text5, A, text6, a to build and display the exponential function graphs and textual information. It is suitable for high school mathematics teaching, helping students understand the properties and graphical characteristics of exponential functions.
