Help me plz

 

For integers $n$, let \[f(n) = \left\{
\begin{array}{cl}
n & \text{ if }n\text{ is odd}, \\
n -1 & \text{ if }n\text{ is even}.
\end{array}
\right.\] Find $f(f(f(f(f(4)))))$.

Find  \(f(f(f(f(f(4)))))\) 

 

f(4) = 4 -1 = 3

f (f(4)) = f(3) =  3

f (f(f(4))) = f(3)  = 3

f(f(f(f(4)))) =  f(3) = 3

f(f(f(f(f(4))))) = f(3) = 3
