**__Lesson 1 - Graphs of Quadratic Functions__** Where do we see parabolas in the real world? Watch this clip to see some examples. media type="youtube" key="rdSgqHuI-mw?rel=0" height="360" width="640" align="center"
 * __The Quadratic Polynomial __** A quadratic polynomial is a polynomial of the second degree. The graph of a quadratic polynomial is called a parabola and for each real number //x// there is one and only one value of //y//. This means that the quadratic polynomial is a quadratic //function//.
