Hey guys, I know what polynomials are but what I really don't understand is the way you are able to find the equation to a set amount of points. I don't understand why you have to have a certain amount of points to find different degrees of functions. For example, why are only three points needed to find a second degree function? And how would I find the equation to a graph if I randomly insert a random point. For example, I have 0,0 1,1 2,4 and then im suppose to have 3,9 but I changed it to 3,16? How would I find this function?(adsbygoogle = window.adsbygoogle || []).push({});
