# Investigation of polynomial functions

With GeoGebra you can investigate roots, local extrema and inflection points of polynomial functions.

        f(x) = x^3 - 3 x^2 + 1
        N = Root[f]
        E = Extremum[f]
        W = InflectionPoint[f]

In Move mode you can drag the function f with the mouse. In this context, the first two derivatives of f are interesting too.

        Derivative[f]
        Derivative[f, 2]
