10-77.

On graph paper, sketch the parabola that is the set of all points equidistant from the focus and the directrix .

  1. Use the definition to write and simplify the equation of the parabola.

    The distance from any point on the parabola, , to the focus is  .
    The distance from any point on the parabola, , to the directrix is √ .

  2. Change the equation of this parabola to shift the graph units to the right.
