Question #eed89

Answer 1

See explanation...

Explanation:

Hello! Alright, to begin this problem, lets go ahead and solve for `y`.

`cancelx+y-cancelx=4-x`

`y=4-x` This also is the same as `f(x)=4-x`

Ok, there are three main steps next. Switch the `x` and `y` variables, then solve for `y`. Finally, put it into inverse notation.

Ok so lets switch the `x` and `y` variables.

`x=4-y`

Solve for `y`

`x-4=4-y-4`

`x-4=-y`

`-x+4=cancel-y/(cancel-1)`

Alright! So the final answer, after we put it into inverse notation, is `f^(-1)(x)=4-x`

Hope that helps!
