In Parabolas, Dr. Eaton first describes what is a parabola with definitions including focus, directrix, and the axis of symmetry. She then elaborates on the vertex as well as the standard form of parabolas which can help with upward or downward opening characteristics. Next Dr. Eaton moves into graphing parabolas using previously learned skills such as completing the square, symmetry, and translation. Furthermore, she instructs you on the latus rectum, how to deal with horizontal parabolas, and finally more elaboration on the focus and directrix. Lastly are four comprehensive examples.
