I introduce the basic structure of Parabolas. After the introductory notes, I work through three examples from easy to the hardest example last. These examples are put into Standard Form before graphing by completing the square when needed.
(FYI ...Latus rectum is Latin for 'right side' or more literally side right)
Also "Latus rectum" is a compound of the Latin latus, meaning "side," and rectum, meaning "straight."
