Hi everybody.(adsbygoogle = window.adsbygoogle || []).push({});

I am in this computer software class and I have a quiz coming up. My professor gave us a list of what to expect on the quiz and this question came up:

Given a family of functions f1, f2, f3, .., fn and given a function f, find the best approximation of f by the family. Best here means you have to minimize an error.

I am thinking it his something to do with least squares or some sort of curve fitting, but I just want to get an idea of what I need to review. This class is hard to study for because it is like a review of every math class I ever taken (and some I have not). Then I have to write certain commands and codes on the software to get the right answers, so its pretty hard.

Anybody got any ideas of what my professor is asking.

Thanks for looking.
