How to convert trendline with E into Excel formula?
How do I write this formula in an Excel cell? y = 4E-11x3 - 3E-07x2 + 0.001x
Formula gives not exact but close to your data result
Please note, if you enter the formula with scientific notation Excel automatically converts such numbers to "number" format where possible.
For example, if you type
after you hit Enter same formula will be shown as
(in A1 is number 2).
Please let me rephrase my question. When I make a scatter plot graph with the above data, add a trend line I get the slope equation of "y = 1E-10x3 - 6E-07x2 + 0.0012x". How do I write this formula in a cell to solve for unknow x values? The response above has 0.8 and then the formula but does not give a result that should be 2,000.
Sorry, I'm missed - where is X and where is Y in your sample? Trendline formula shows how for known X calculate Y, not an opposite. Depends on that you may use any of formulas like
