Question

for the function f(x)= x+9, find (f o f inverese)(5)

Answer 1

\[f\circ f^{-1}(x)=x\]

Answer 2

I need to solve that. x+9 is function f, i dont know how to get the inverse of the function, and the x in ( ) is a 5

Answer 3

@taydub10 it makes no difference
\[f\circ f^{-1}(x)=x\] and so
\[f\circ f^{-1}(5)=5\]

Answer 4

Okay, thankyou
