polynomials are continuous



Given a polynomial P[X]P \in \mathbb{R}[X] over the real numbers, we may regard it as a function P:P \colon \mathbb{R} \longrightarrow \mathbb{R}. If here \mathbb{R} is regarded as a Euclidean space (equipped with its metric topology), then this is a continuous function.


The proof using epsilontic analysis is spelled out for instance in
