Find the inverse of the function by reversing compositions f(x)=5x+8 F^-1 (x)

Sagot :

The function is given .

[tex]f(x)=5x+8[/tex]

To determine the inverse of the function , we have to swap or reverse the variables x and y.

[tex]y=5x+8[/tex]

After reversing the composition.

[tex]y-8=5x[/tex][tex]x=\frac{y-8}{5}[/tex]

Thus the inverse of the function is,

[tex]F^{-1}(x)=\frac{y-8}{5}^{}^{}[/tex]
