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

Suppose y is related to x by some function, or:

y = ƒ(x).

Now, supposing that we know some values for y and the corresponding values for x, would it be possible to find what the function actually is?

And if so, how would it be done, without any computer programs. (i.e, what process should be followed to do it)

Thanks for any answers
