The "new_x" values are in cells A24:C24, where B24 and C24 are the formulas as shown. The "known_y" values are in green in E3:E22 expression A variable that represents a Trendline object. Setting this property to True automatically turns on data labels. The "known_x" values are in green in A3:C22 True if the equation for the trendline is displayed on the chart (in the same data label as the R-squared value). If you change the values in E3:E22, the trend() function will update Cell E24 for your new input at Cell A24.Įdit = For making a trend line, two sets of variables are required: an independent, predictor, or explanatory variable x (named as knownx's ), a dependent or response variable y (named as knowny's ). 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.
