    Polynomials (LINEST)

    Please see attached file.

    My "calculated" polynomial is not the same as the Trend line on the graph. The one on the graph seems to be correct.

    Basically, I am using the LINEST function to create a polynomial equation inorder to extrapolate data. And also with a given equation, and a given y, find x

    Thanks for any help.
