lambda calculus typed forms

A term t is typable if there is a context Γ and a type τ such that the judgement



" Γ ⊦ t : τ " is derivable.



How do I indicate if the expression " f -> x -> f (f (f x)) " is typable or not?



And can anyone explain to me what normal and neutral forms of lam are?



Thank you
