Question

Find the inverse of each function, if it exists.
f(x)=x+12/7

Answer 1

If the function is
`f(x) = x + (12)/(7)`

the inverse is
`f^(-1)(x)=x-(12)/(7)`

However, if the function is
`f(x) = ((x+12))/(7)`

the inverse is
`f^(-1)(x)=7x-12`

Explanation:

If the function is
`f(x) = x + (12)/(7)`

the inverse is
`f^(-1)(x)=x-(12)/(7)`

However, if the function is
`f(x) = ((x+12))/(7)`

the inverse is
`f^(-1)(x)=7x-12`
