Question

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

Answer 1

The function is given .

`f(x)=5x+8`

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

`y=5x+8`

After reversing the composition.

`y-8=5x`
`x=(y-8)/(5)`

Thus the inverse of the function is,

`F^(-1)(x)=(y-8)/(5)^{}^{}`
