Math: Defining unknown functions.

[Psionicist]

Lets say we know f = 1, 8, 27, 58, .... f is unknown and undefined. One of many functions f can be is for example 6n^2-11n+6.

What's the name of creating/generating a function from an arbitrary number of return values? I don't remember the word and it's really annoying!

Thanks.

extrapolating?

Usually "curve fitting", sometimes "regression"; "interpolation" if you're just estimating values in between the known points and "extrapolation" if you're estimating values outside the range.
