Hi!
I'm woriking on extrapolation a graph in excel. I have used a trendline doing so, and I get an polynomial 6. degree that fits quite ok. The problem is I don't know how to use the trendline equation.
y = -1E-17x^6 + 5E-14x^5 - 8E-11x^4 + 6E-08x^3 - 2E-05x^2 + 0,002^x + 5,066
When I'm entering, say vaules for x = 1390 ; y should be around the value of 2.3, but my interpretation of the equations can't be right.
Is there any better way / more understanding way to write this equation? What does E stand for her? Is it the same as 10^? and if so, what is the power to 10?
Thanks
Mesut
