Intro to Square Root Function Rule

This example demonstrates how to determine the rule of a square root function given its vertex and one point. Key math concepts include square root functions, vertex coordinates, and linear equations. GeoGebra commands used are Point for creating points B, C, D, E, F, G, along with objects like text1 to text6 and variables a, b for labeling coordinates and parameters. Suitable for middle school and above students learning function graphs and analytical geometry.
