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/Minimum Vertex/ Maximum Axis of Symmetry Parabolas Quadratic Sequences Quadratic sequences take the form рќ’Џ + рќ’Џ+ For each of the following quadratic sequences, identify the values of a, b and c:
