Fit an exponential regression and calculate the inflection point in Excel

How to fit an exponential regression and calculate the inflection point of the fitted curve (more especifically the point in X axis in which the inflexion occurs), all in Excel. An inflection point, point of inflection, or inflection (inflexion) is a point on a curve at which the curvature changes sign In other words, the inflection point is the point of the curve at which there is a significant move. I have cheked in SPSS and it is correct!! :)

Thanx a lot, I have been looking for this since a week! it was very helpful!

Please take this video off. There is no point of inflection on your graph.. Concavity or CURVATURE must change in order to have a point of inflection. Your graph is completely concave up. Please take this video down.

He is not going to take it down you idiot. It is still helpful.

I was enforced to review basic concepts just to confirm your statement "the inflection point is the point of the curve at which there is a significant move" is not accurate enough and there is no sense in stating that the intercept bethween your best fit and the original graph is an inflexion point. You must ALWAYS find at least one common point between both, but your graph does not have a point in which curvature changes. It's always pointing up

Not an inflection point.
