In mathematics, a continuous function is a function such that a continuous variation (that is a change without jump) of the argument induces a continuous variation of the value of the function. This means that there are no abrupt changes in value, known as discontinuities. More precisely, a function … 查看更多內容
A form of the epsilon–delta definition of continuity was first given by Bernard Bolzano in 1817. Augustin-Louis Cauchy defined continuity of $${\displaystyle y=f(x)}$$ as follows: an infinitely small increment 查看更多內容
The concept of continuous real-valued functions can be generalized to functions between metric spaces. A metric space is a set $${\displaystyle X}$$ equipped with a function (called 查看更多內容

https://zh.wikipedia.org/wiki/连续函数连续函数(英語:Continuous function)是指函数在数学上的属性为连续。直观上来说,连续的函数就是当输入值的变化足够小的时候,输出的变化也会随之足够小的函数。
如果输入值的某种微小的变化会产生输出值的一个突然的跳跃甚至无法定义,则这个函数被称为是不连续函数,或者说具有不连续性。非连续函数一定存在 …Wikipedia · CC-BY-SA 授權下的文字- 預估閱讀時間: 6 分鐘
