I have created a graph on excel and have tried to extract the polynomial (I think that is what it is) but excel tells me the wrong polynomial.
Please open the doc file and extract the polynomial from the graph's data. The first graph is the graph I need the polynomial for. The second is the polynomial that excel gives me which is incorrect.
The first lot of data is for the graph that I want the polynomial for. The second lot of data is the data from the polynomial that excel gave which is incorrect.
This is for private purposes and not for schooling of any type.
I would greatly appreciate your help.
