To most people, “a rule that assigns each input exactly one output” is perfectly clear. But the formal set-theoretic definition—while precise and necessary for rigorous proofs about foundations—introduces jargon (subset, Cartesian product, unique existence) that turns a simple idea into something that looks like abstract nonsense. For a high school student meeting functions for the first time, this level of formalism is unnecessary obscurity, not clarity.“A function ff from a set XX to a set YY is a subset of the Cartesian product X×YX×Y such that for every x∈Xx∈X, there exists a unique y∈Yy∈Y with (x,y)∈f(x,y)∈f.”
