Homework Statement
Hey, been having a lot of hmwk troubles. I haven't really been taught logistic functions or things relating to the matter. I need to figure out an accurate growth rate formula, and to me it seems to be like an exponential.
Note: this is like a table of X and Y coordinates. The maximum the length ( x value) can go to is around 80cm.
Length (cm). 10.1 25 32.6 35.4 43.8 45.5 55.7
Weight (g)... 16 244 542 695 1319 1479 2720
Homework Equations
I'm guessing the logistics equation?
c/ [1 + Ae-bx]
and
1/[1 + e-x]
The Attempt at a Solution
I don't really have a clue. I typed it into my calculator, then used the stat function to find a formula for me. It came up with:
5091/[1 + 221.8e-0.1X
However, I have no idea how the values were calculated. The constant keeps changing, and I've tried using f(x) = arx. But that doesn't work either.
Could someone please help me out? Maybe put it into simple terms? All googling about logistics haven't helped me at all :/
