  1. Parabolas Ch10.2 and additional material

  2. Conic Sections - Parabola The latus rectum is the line segment passing through the focus, perpendicular to the axis of symmetry with endpoints on the parabola. LatusRectum Focus Vertex(h, k)

  3. Conic Sections - Parabola The length of the latusrectum is 1/|a| The focal length is c=1/(4|a|) LatusRectum Focus Focal length (c) Vertex(h, k)

  4. Table of Rules : y = a(x - h)2 + k

  5. Table of Rules : x = a(y - k)2+ h

  6. Ex) Find the vertex, axis of symmetry and direction of opening.

  7. Ex) Graph

  8. Ex) Find the min/max value, the length of the latus rectum, and intercepts on the axis perpendicular to the axis of symmetry.
