MIT grad explains how to find the vertex of a parabola. This is a simple, fast way to identify the vertex, taken either from the equation of a parabola in "standard form," or from the equation in "vertex form." More videos with Nancy coming in 2017!
The equation of a parabola is a quadratic equation and can come in either standard or vertex form. For each form, I give you an easy method to calculate the parabola vertex point. As a separate question, if you want to be able to convert your standard form into vertex form with a perfect square in your equation, you will need to "complete the square" first to get your parabola equation into vertex form. If you need help completing the square, check out my video on that: http://youtu.be/bclm1tJB-3g
Graphically, in geometry the vertex is either the lowest point on the parabola (the minimum) if the parabola is opening up, or it is the highest point on the parabola (the maximum) if the parabola is opening down.
