That's a terrible way to post questions. It gives us SPAM, and we can't
copy/paste the code from PDF to Mathematica.
You should have copy/pasted the code from Mathematica to e-mail. (Simple.)
But here's the code:
f[x_] = 4/Sqrt[Pi] -
0.3353/(.435404 + x)^2 + .347025/(.712229 + x)^4 - .270017/(
4.29043 + x);
data = Table[{Sqrt[10^i], f[Sqrt[10^i]]}, {i, -7, 1, 0.1}];
Show[ListPlot[data, PlotRange -> All],
ParametricPlot[{Sqrt[x], f[Sqrt[x]]}, {x, 10^-7, 10}]]
It does NOT give the plot shown in your PDF, and there's no mismatch
between the points and the curve.
