Question: Curve fitting for function and experimental data

Hi 

friend i want fit a curve regarding some data and fnction and how we can find the values of a,b,c and d for the following 

f=1-(8*a*b+6*c*d/(b*k*x))/(2*a*b+c*b*(1/(b*k*x)))

X := Vector([200, 210, 220, 230, 240, 250, 260, 270, 280, 290])

Y := Vector([.4172, .3030, .4668, .3317, .1276, .1303, .1733, .1451, .3466, .4125])
