Question

What is the inverse of f(x) = x + 2?

Answer 1

inverse of
`f(x)=x+2` is
`x-2`

Explanation:

To find the inverse of given function, we replace
`f(x)` by y

`y=x+2`

interchanging x and y we get

`x=y+2`

then separating the variable y we get

`y=x-2`

again replace y by
`f^(-1)(x)`, we get

`f^(-1) (x)=x-2`

and we complete the question·
