I have three key points on a graph. How do I find out what the formula for this graph would be? The points are: (3,0) (5,2) (7,6). It is known that the graph will be a quadratic. Thanks
You can try
The graph can be generated by:
For your case, another approach is to solve the equations generated by the given points:
Of course, this solution will not work if the number of points increases and some of these points are not located on the curve.
