Exponents of 2: Positive, Negative, Zero by Terry Lee Lindenmuth

This example demonstrates the graphical representation and variation patterns of positive, negative, and zero exponents of 2. It involves core mathematical concepts such as exponent operations, function graphs, sequence changes, and inequality representation. The construction uses GeoGebra commands like Text to label objects f, X, Y, text1, text2, text3, text2_1, text4, text5, A, text6. It is suitable for middle school and above students to learn and understand the properties of exponential functions, as well as for high school mathematics teaching demonstrations.
