Find the composition function

that can be form from two this

single functions below :

f (x) = 2 x + 4

g (x) = \frac{2 x - 7}{3 x}

∙ fog (x) = \dots \dots .

∙ gof (x) = \dots \dots

∙ fog (x) = 2 (\frac{2 x - 7}{3 x}) + 4

fog (x) = \frac{16 x - 14}{3 x}

∙ gof (x) = \frac{2 (2 x + 4) - 7}{3 (2 x + 4)}

gof (x) = \frac{4 x + 1}{6 x + 12}
