Find the composition function  that can be form from two this  single functions below :  f(x)=2x+4   g(x)= ((2x−7)/(3x))  • fog(x)=.......  • gof(x)=......

•fog(x)=2(((2x−7)/(3x)))+4  fog(x)=((16x−14)/(3x))    •gof(x)=((2(2x+4)−7)/(3(2x+4)))   gof(x)=((4x+1)/(6x+12))

$$\bullet\mathrm{fog}\left(\mathrm{x}\right)=\mathrm{2}\left(\frac{\mathrm{2x}−\mathrm{7}}{\mathrm{3x}}\right)+\mathrm{4} \\ $$$$\mathrm{fog}\left(\mathrm{x}\right)=\frac{\mathrm{16x}−\mathrm{14}}{\mathrm{3x}} \\ $$$$ \\ $$$$\bullet\mathrm{gof}\left(\mathrm{x}\right)=\frac{\mathrm{2}\left(\mathrm{2x}+\mathrm{4}\right)−\mathrm{7}}{\mathrm{3}\left(\mathrm{2x}+\mathrm{4}\right)} \\ $$$$\:\mathrm{gof}\left(\mathrm{x}\right)=\frac{\mathrm{4x}+\mathrm{1}}{\mathrm{6x}+\mathrm{12}} \\ $$
