Like the topic says, is there some software or method you can use (maybe excel?) to create equations?
For example if i knew my graph is going to be a straight line, and i had a few points, i can find the slope, intersection and get my equation.
Then if i knew my graph is a 2nd order and i had a few points like x=2, y=4, x=3 y=8 etc then i can probably guess it is y=x^2
But what if my graph looks like a 2nd order, and the numbers are all over like 2.111, 7.555 etc and how do you get a best fit equation to describe your x and y equation. because the answer maybe y=ax^2 + bx + c and with 10 valid points it may take a long time to get that best fit line equation.
Thanks
