什么是 Reference functions？

又称： hyperbola

Definition 11.3 High School Mathematics · 第 11 章 — Functions and Variations

x \mapsto x^2 \text{ (square)}, \quad x \mapsto x^3 \text{ (cube)}, \quad x \mapsto \sqrt{x}, \quad x \mapsto \frac{1}{x}, \quad x \mapsto \abs{x}.

Their domains are $\R$ , $\R$ , $\intco{0}{+\infty}$ , $\R \setminus \{0\}$ and $\R$ respectively. The curve of $x \mapsto \frac1x$ is a hyperbola.

The five reference curves: the parabola x2 and the cube x3 (left); √ x, x and the hyperbola 1x (right). — The five reference curves: the parabola $x^2$ and the cube $x^3$ (left); $\sqrt x$ , $\abs x$ and the hyperbola $\frac1x$ (right).
