Add to ORKGAbstract. Let A be a closed Gδ-subset of a normal space X. We prove that every function f0: A → R with a closed graph can be extended to a function f: X → R with a closed graph, too. This is a consequence of a more general result which gives an affine and constructive method of obtaining such extensions
