As already noted by some of the answers, an interpolating polynomial might not necessarily be the best idea. You might want to look at a piecewise interpolating polynomial, for which Mathematica has the Interpolation[] function.

@BOMEz a useful and necessary skill is to be able to search within the documentation itself, and not via google. Obviously, you know the answer now, but try searching for "interpolating polynomial" in the documentation center and see what you get. I got to it by going through InterpolationFunction and seeing the related functions.

| Oct 10, 2012 at 12:45 | comment | added | BOMEz | @J.M. I believe I want interpolation... I have a set of values and would like to get the best guess of the ranges in between those values. | |
| Oct 10, 2012 at 12:45 | comment | added | BOMEz | @rcollyer I did do some searching on my own using Google and ended up on the Mathematica online help. The results I got to though didn't give me what I was looking for.I was confused because I couldn't just get a straight forward formula like I could on Wolframalpha. From the responses below it seems more involved and when I felt I was in over my head I decided to ask. | |

| Oct 9, 2012 at 19:11 | comment | added | Searke | Once you write out the equations for coefficients of the polynomial, it becomes a linear algebra problem with a vandermonde matrix en.wikipedia.org/wiki/Vandermonde_matrix reference.wolfram.com/mathematica/ref/… Or you can use the documentation center and search for Interpolation. | |

| Oct 9, 2012 at 19:05 | comment | added | rcollyer | Have you tried using the Documentation Center under the Help menu? I found the answer in there, but I'd like to know you've done a little searching yourself, first. | |
