Root Command From GeoGebra Manual
Root( ) Yields all roots of the polynomial as intersection points of the function graph and the xaxis. Example: Root(0.1*x^2 - 1.5*x + 5) yields A = (5, 0) and B = (10, 0).
Root( , ) Yields one root of the function using the initial value a for a numerical iterative method. Example: Root(0.1*x^2 - 1.5*x + 5, 6) yields A = (5, 0).
Root( , , ) Let a be the Start x-Value and b the End x-Value . This command yields one root of the function in the interval [a, b] using a numerical iterative method. Example: Root(0.1x² - 1.5x + 5, 8, 13) yields A = (10, 0).
CAS Syntax Root( ) Yields all roots of the polynomial as intersection points of the function graph and the xaxis. Example: Root(x^3 - 3 * x^2 - 4 * x + 12) yields {x = -2, x = 2, x = 3}. Note: In the
CAS View, this command is only a special variant of Solve Command.
