Answer 1

Answer: C)
`f^(-1)(x)=3-7x`

Explanation:

When solving for an inverse of a function replace f(x) with x and replace the original x with y.

`f(x) = (3-x)/(7) \\x=(3-y)/(7)`

Now solve for y

`x=(3-y)/(7) \\(7)x=((3-y)/(7)) (7)\\7x=3-y\\7x+y=3-y+y\\7x+y=3\\7x-7x+y=3-7x\\y=3-7x`

Replace y with the
`f^(-1)(x)`
