    Study Notes

    Quadratic Function Forms

    • The vertex form of a quadratic function is equivalent to the factored form.

    Identifying Key Features

    • The factored form of a quadratic function allows for easy identification of the x-intercepts.
    • The vertex form of a quadratic function allows for easy identification of the vertex.

    Purpose of Rewriting Quadratic Functions

    • Rewriting a quadratic function from standard form to vertex form helps to identify the vertex and axis of symmetry of the parabola.
    • Rewriting a quadratic function from vertex form to standard form helps to identify the zeros or x-intercepts of the quadratic equation.
