These extrapolations are technically beyond the limits of careful and orderly scientific work, a discipline of study that is properly limited to the study of physical objects andor events of the present. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results. For a quadratic interpolation either use the points x0, x1 and x3 or the points x1, x3 and x4. As we have seen, this type of extrapolation is merely conjecture and may lead to serious errors.
