1. Find the x-coordinate of the vertex
Graph Quadratic Equations
The graph of a quadratic equation y = ax2 + bx + c is a parabola.
If a is positive  parabola opens up
If a is negative  parabola opens down
The highest or lowest point on the graph is called a vertex.
The parabola is symmetrical about the vertical line through the vertex. It is called an axis of symmetry.
The vertex has an x-coordinate of
