Re: equation of a graph

but i want to find *"best-fit curve" *


What type of curve?  Polynomial (of which your rejected linear is 
a low-order variant)?  Exponential or logarithmic?  Bell curve? 
S-curve?  Circle?  Axis-aligned ellipse? non-axis-aligned 
ellipse?  There are lots of curvy possibilities here...

eight, Piecewise of eight" and "Polynomial want a cracker")

equation of a graph

[ankita dutta]

hii..

i am working with graphs,
my problem is to find the equation for any given graph.

i tried with  *"polyfit" function*.
but that only give me the slope and y-axis intercept. hence *"best-fit
line" *   ,
but i want to find *"best-fit curve" *

how can i find that ?
