Question

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

Answer 1

Answer:

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

Step-by-step 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·
