Resposta:
[tex]F^{-1} (X)=\frac{1}{4} x+\frac{3}{4}[/tex]
Explicação passo a passo:
[tex]F(x)=4x-3\\Substitua F(x) por \\\\y= 4x-3\\\\x=4y-3\\\\4y-3=x\\\\\\4y=x+3\\\\\\\frac {1}{4}x+\frac{3}{4} \\\\Substitua\\y=F^{-1} (x)=\frac {1}{4}x+\frac{3}{4}\\\\Solucao=F^{-1} (x)=\frac {1}{4}x+\frac{3}{4}[/tex]
