How to Graph Quadratic Equations?
To graph simple quadratic equations, you can substitute x values to find corresponding y values, and then plot the graph with these x and y points. However, for more complicated problems, you can first find the vertex of the quadratic equation given by formulas, and then substitute x values to find corresponding y values. You then simply plot these points on the graph. You can find more information here: http://www.purplemath.com/modules/grphqu…
