How about I start with y = -7E-22x6 + 8E-16x5 - 3E-11x4 - 2E-07x3 - 0.0587x2 + 2746.9xLike I said, learn some maths and come up with the answer yourself.
Start with y = a(1 + r)^x
I am well aware that I am taking the piss with fitting a polynomial trendline but the trend is tending upwards, I've just exaggerated the curvature of the trendline for effect
Disclaimer... Last serious Maths study that I undertook was undergrad 2nd year about...... 18 years ago (shit.. I'm getting old)
