A piecewise function, also known as a piecewise-defined function is a function that has a different rule depending on the intervals found in the domain of the function. When working with piecewise functions, be careful when determining the domain and the range (more specifically, if there are ...
定义分段线性函数。 不是纯线性而是由线性分段组成的函数的约束非常容易地表示了一些问题。 此类函数也被称为分段线性。 在此主题中,传送示例向您显示了适用于分段线性模型的各种表述和解决问题的方式。 在陷入问题前,此部分定义了此讨论中显示的一些术语。 从几何学角度来看,图 1显示了传统的分段线性函数f(x)。
is continuous. This example illustrates that everywhere differentiability is a significantly stronger property than almost everywhere differentiability. We will see further evidence of this fact later in these notes; there are many theorems that assert in their conclusion that a function is almost everywh...

Does there exist a differentiable function f that satisfies f (0) = 2, f (2) = 5, and f'(x) less than or equal to 1 on (0, 2)? If not, why not? Find all values of x where the function shown below is n...
If we were to graph the above, we would get a continuous graph without any discontinuities. When you see functions written out like that, be sure to check whether the function really has a discontinuity or not. Sometimes the function is continuous but just written like it isn’t just to ...
Continuity in a Point: A function is continuous at a point if: 1) The one-sided limits exist and are the same, in which case the limit exists. 2) The value of the limit coincides with the value of...
Spline Interpolation:A method for predicting the value of a function at a position between two known data points by locating a smooth curve that passes between the data points and has continuous derivatives up to a particular order. Cubic Interpolation:Determining a cubic polynomial that crosses thr...
The key observation that makes the above equivalences work is that this relation is continuous in the sense that if is an open subset of , then the inverse image is also open. Indeed, if for some , then contains a finite set such that , and then any that contains both and lies in ...
