Diketahui fungsi  f(x)=(2x4)(5x), x5f(x)=\frac{\left(2x-4\right)}{\left(5-x\right)},\ x≠5  dan g (x)=3x+7. Fungsi invers dari (g∘ f) (x) adalah ⋯⋅

 (gf)1(x)=(5x23)(1+x)(g∘f)^{-1}(x)=\frac{\left(5x-23\right)}{\left(-1+x\right)}  

 (gf)1(x)=(5x+23)(1+x)(g∘f)^{-1}(x)=\frac{\left(5x+23\right)}{\left(-1+x\right)}  

 (gf)1(x)=(5x+23)(1+x)(g∘f)^{-1}(x)=\frac{\left(5x+23\right)}{\left(1+x\right)}  

 (gf)1(x)=(5x23)(1+x)(g∘f)^{-1}(x)=\frac{\left(5x-23\right)}{\left(1+x\right)}  

 (gf)1(x)=(5x23)(1+x)(g∘f)^{-1}(x)=\frac{\left(-5x-23\right)}{\left(1+x\right)}
