Working with quadratic functions can be less complex than working with higher degree functions, so they provide a good opportunity for a detailed study of function behavior. Recognizing Characteristics of Parabolas I. Quadratic Functions A. The basics The graph of a quadratic function is a parabola. A parabola for a quadratic function can open up or down, but not left or right. The vertex is either the highest or lowest point on the graph depending on whether it opens up or down. If the parabola opens down, the vertex is the highest point. y x Vertex ...
