I am not sure if we change the lower limits, How to use the Gauss–Laguerre quadrature. I am considering about substitution the lower limits. It looks like $$\int_{0}^{\infty}{{e^{-(x-10)}}f\left(x-10\right)}\,\mathrm{d}x=\sum_{i=1}^{n}w_{i}f\left(x_i-10\right)?$$
I am not sure it is right. And how the $w_{i}$ and $x_i$ will be changed ?
