23.3.2 The Vertex: Highest or Lowest Point

Core idea

The bottom (or top) of the bowl is where the curve turns, and its coordinates (h,k) fix where the whole curve sits.

Module goal. Move from vertex form to the general form, and master how to find the three geometric essentials along with the graph's properties.
