Plot of Data 
The first step in fitting a nonlinear function is to
simply plot the data.
This plot initially shows a fairly steep slope that levels off to a more gradual slope. This type of curve can often be modeled with a rational function model. The plot also indicates that there do not appear to be any outliers in this data.
