I have 5 x axis values and 5 y axis values..
now i want to fit the equation
f(x)=a*(x^b - 2^b)
after that i have to plot the 5 data points which i did like plot(x,y)
now i have to plot my fitted function also on the same plot and it should be a smooth curve.
please help me..

Did you consider the use of curve fitting tool?

On the command window, type:

the fitting function are part of the curve fitting tool. If you don't have it, you have to code the fitting algorithm yourself.
