Graphs

hi Kgirl

what does a logistic graph look like?

f(x) = 1 / (1+e ^-x)

And here is an artical about it.

This stuff under here is probably irrelevant but I did it before I realized so I'll just leave it there now.

Or did you meant what do logarithmic graphs look like?
Here are 2 examples.

----------------------------------------

do you know what y = 10 ^x looks like?
and, do you know what y=x looks like?
If you reflect y=10 ^x across the line y=x then the new curve will be y=log x (that's y=log of x base 10)

I'll see if I can draw the graphs to show you.

There you go, can you see how they are reflections of each other? Graphs that reflect across the line y=x are called inverse graphs.

I hope that I have answered your question.
