Discovering Properties of Parabolas by Comparing and Contrasting Parabolic Equations

  • Teachers can use this resource to teach students how to derive the equation of a parabola in vertex form y = a(x – h)2 + k, when given the (x, y) coordinates of the focus and the linear equation of the directrix.
  • An additional interactive graphing spreadsheet can be used as a resource to aid teachers in providing examples.
