Square Root Function Graph and Its Properties

① This example visualizes the graph of the square root function y = sqrt(x), illustrating its shape, domain, and range on the coordinate plane. ② Core mathematical concepts include the definition and notation of the square root function, curve sketching, and an introductory link to its derivative. ③ The construction uses GeoGebra objects such as the function f(x) = sqrt(x) and text labels (text1‑text4) to annotate key points, with optional sliders for interactivity. ④ It is intended for high‑school algebra and pre‑calculus students, as well as for middle‑school enrichment activities to deepen understanding of square root functions.
