The 'known_x' values are in green in A3:C22 If you change the values in E3:E22, the trend() function will update Cell E24 for your new input at Cell A24.Įdit = The trend() formula is in Cell E24 where the cell references are shown in red.Ĭell A24 contains the new X, and is the cell to change to update the formula in E24Ĭell B24 contains the X^2 formula (A24*A24) for the new XĬell C24 contains the X^3 formula (A24*A24*A24) for the new X Column C is X^3 (two cells to the left cubed).
Column B is X^2 (the cell to the left squared). Try trend(known_y's, known_x's, new_x's, const).Ĭolumn A below is X.
