# Fit several inverse functions to cloud of points

I have a cloud of points that can be clustered so that each set of points in the cluster can be fitted with an inverse function : $f(x) = cte / x$.

What would be an approach for clustering my dataset when discrimining criteria is fit to an inverse curve. I am on the computational side, I am looking for a simple fitting algorithm for a beautiful display with curves that are fitting the data thus demarcating several cluters of points.
