Hi my first post , I hope I chose the right forum?(adsbygoogle = window.adsbygoogle || []).push({});

I'm here looking for a memory jog not for someone to do my work, I'm trying to remember how to find the f(x) to complete this chart , there is many more data points but I'm just providing you with the top line , I shall do the rest myself, can someone help me please?

It's been many years since I attempted this problem :(

x y x^2 xy f(x) f(x)-y (f(x)-y)^2
