This is the standard form of a quadratic function with h = - b / 2a k = c - b 2 / 4a When you graph a quadratic function, the graph will either have a maximum or a minimum point called the vertex. The x and y coordinates of the vertex are given by h and k respectively.... Need some help identifying quadratic equations first? Identifying Quadratic Equations A quadratic equation is an equation of the form [beautiful math coming... please be patient] $\,ax^2 + bx + c = 0\,$, where $\,a \ne 0\,$.

GeoGebra can be used very easily to find the equation of a parabola: given three points, A, B, C input the command FitPoly[{A, B, C}, 2]. There is also a spreadsheet, which can be used as easily as Excel.... In the first two examples there is no need for finding extra points as they have five points and have zeros of the parabola. In example 3 we need to find extra points. The equation is y=4xsquare-4x+4. You can take x= -1 and get the value for y. You will get a point now. Similarly you can substitute -2 for x in the same equation and get the value for y. Now you get another point. Now you can
