I have some sample data, I draw a trending line which gives me equation as well. But I found that the trending line sometimes isn't trustworthy at all.
The trending line graph doesn't match the equation!
I think that's unacceptable and totally out of my expectation. Why is it?
count(x) runtime(y) 1000 0.1 2000 0.8 4000 6.4 8000 51.1
How to reproduce it: Draw a scatter plot, add a trending line, choose Exponential. Then try to calculate by the given equation, when
8000. And you can see
y doesn't match the graph at all.
