In this lesson I define Quadratic Functions in the form of y=ax^2+bx+c, identify the vertex, and graph a parabola using a t-table. I also discuss the definition of a Polynomial and Degree. We then identify Increasing and Decreasing Intervals, Domain and Range, End Behavior, and Absolute Maximum and Absolute Minimum
