The idea of interpolation is to use the behavior of a set of discrete points to "guess" what could be happening in the intervals inside that set. This uses the information given by the points within the range they encompass. Extrapolation is in fact meaningless unless you assume that outside the range of the given set the behavior of additional points will be the same as within the range. Try for example In[1]:= g = Interpolation[{2, 4, 6, 10}] Out[1]= InterpolatingFunction[{{1, 4}}, <>] This gives you a "guess" within the range {1, 4}. Then try to evaluate for example g[11]. You get a warning message that 11 lies outside the range and will give you then an "extrapolated" guess. T'is up to you to buy it or not.
