106 反函數 Inverse Function
- long x \(\ln x\)
- swap x and y 對調 \(x\) 和 \(y\)
- bijective / bijection 雙射(形容詞、名詞)
- natural domain 自然定義域
- continuous function 連續函數
- strictly increasing 嚴格遞增
- strictly decreasing 嚴格遞減
- horizontal line test 水平線檢驗
- vertical line test 鉛直線檢驗
- one-to-one and onto 一對一且映成
- The inverse of f inverse is f. \(f^{-1}\) 的反函數是 \(f\)
- The set of real numbers x such that f of x exists. \(\{x\in \mathbb{R}\ \mid f(x)\text{ exists}\}\)
- The inverse of f exists if and only if f is bijective or f is a bijection. 若且唯若 \(f\) 是雙設函數,則 \(f\) 有反函數。
- The vertical lines intersect the curve in at most one point. 曲線與鉛直線至多只有一個交點。
- The graphs of inverse functions are symmetric about the line y is equal to x. 函數與其反函數的圖形對稱於 \(y=x\) 直線
