Exponential curve Watch
For the equation y = 1 / (1+9exp(-x)) I seem to get an S like shape from x=0 to x=8, with the head continuing along the line y=1. There's supposed to be something to observe at y = 0.5, but as far as I can see there's nothing remarkable, except that its virtually linear at this point. Should I be noticing something further?
Put in "1 / (1+9*exp(-x))"
I suppose it's a sort of point of inflection. I could be wrong. I'm not sure of the exact definition of one, but I've only seen them where positive gradients meet negative ones.
