Lemma 37.72.5. Let $f : X \to Y$ be a locally quasi-finite morphism. Then

**Proof.**
Agreement of the functions is immediate from the fact that the (geometric) fibres of a locally quasi-finite morphism are discrete, see Morphisms, Lemma 29.20.8. Boundedness follows from Morphisms, Lemmas 29.56.2 and 29.56.9.
