## Main Question or Discussion Point

As we know, a quadratic function can be expressed in a form of complete square by a method of completing the square. This form enables us to prove that a quadratic equation is symmetric about its stationary point.

But for the cubic function, is there a similar way to prove that the cubic curve is inversely symmetric about its point of inflection?? (meaning to prove that the curve on each side of the inflection point is inverted but perfectly matched )

Thanks a lot
