Mathematical analysis is the systematic study of real and complex-valued continuous functions.

Handouts:
Real function $f: \mathbb{R} \mapsto \mathbb{R}$ is a mapping between subsets of the real line. Real-valued function $f: X \mapsto \mathbb{R}$ is a mapping whose codomain is the real line. Function of a real variable $f: \mathbb{R} \mapsto X$ is a mapping whose domain is the real line.
Support $\mathrm{supp}(f)$ of a real-valued function $f: X \mapsto \mathbb{R}$ on a topological space $(X, \mathcal{T})$ is the closure of the subspace where $f$ is not zero: $\mathrm{supp}(f) := \overline{\{x : f(x) \ne 0\}}$.
