How to Find the Coordinates of the Vertex
This video shows how to find the x-coordinate of the vertex for a quadratic equation. There are a few different ways to find the x-coordinate of the vertex. The easiest way is simply to remember that the x-coordinate of the vertex is always equal to -b/2a, where a is the coefficient of the x2 term and b is the coefficient of the x term. You could also sketch a graph using ordered pairs and try to eyeball where the vertex would be. You could also use the ordered pairs to find the equation for the parabola and then convert in into vertex form.
