yes. You can by adding an adiditonal column that contains the polynomial (from the trnedline) that operates on the same x values:
As you can see the predicted column extends beyond the original data. Extrapolating data should be done very carefully as it is "precidting"
In the table I added the column (C) with the title "Predicted" and added a formula that is the same as the reported trendline:
Then I filled down
Just wondering what formulas are used in Badunit's tables, as per my last message.
The same as Wayne used in C2 in his example except instead of typing the coefficients into the formula, you reference them from cells F2-H2.
