Let f and g be two real valued functions with domain $\mathrm{A}=\{-2,0,2\}. \mathrm{If} \mathrm{f}=\{(-2,4),(0,6),(2,8)\}$ and $\mathrm{g}=\{(-2,-1),(0,3),(2,5)\},$then $(\frac{\left(2\mathrm{f}\right)}{\left(3\mathrm{g}\right)}+\frac{\left(3\mathrm{g}\right)}{\left(2\mathrm{f}\right)}-6)\left(0\right)=$
