Is it possible to use Wolfram Alpha to make something like this into a graph and have it display the proper function?
In that case, how would I syntactically write it in Wolfram?

1Can you see what the proper function is yourself? It isn't too hard. – Zev Chonoles Jun 02 '13 at 10:38

Yes xD, I'm just using this as an example. – Jonathan Jun 02 '13 at 10:45

If you have a large amount of data, you might try WolframAlpha Pro, which has allows you to upload files and has an Excel-like entry mode. If you're curious, I could post an answer with screenshots. – Mark McClure Jun 02 '13 at 16:10

If you just want to plot the points, then you can use
plot {{1, 12}, {3, 36}, {5, 60}, {7, 84}, {9, 108}}
If you want to try and approximate the function, then you can use
interpolate {{1, 12}, {3, 36}, {5, 60}, {7, 84}, {9, 108}}
Of course, this isn't going to give you the exact function that you're looking for every time (this happens to be a nice example), but it will give an approximate polynomial based upon the data that you feed in.

1Nice. As you note, these points just happen to be collinear. You might also try
fit, rather thaninterpolate, particularly when the points are not collinear. – Mark McClure Jun 02 '13 at 16:09
