WebMar 10, 2024 · It’s possible for a function to be continuous but not differentiable. (If needed, you can review our full guide on continuous functions.) Let’s examine what it means to be a differentiable versus continuous function. For example, consider the absolute value function f (x) = ∣ x ∣ f(x) = \vert x \vert f (x) = ∣ x ∣ below. WebSep 5, 2024 · Remark 4.7.7. the product of two convex functions is not a convex function in general. For instance, f(x) = x and g(x) = x2 are convex functions, but h(x) = x3 is not a convex function. The following result may be considered as a version of the first derivative test for extrema in the case of non differentiable functions. rockman switch

可微分函数(英語:Differentiable function)在微积分学中是指那些在定义域中所有点都存在导数的函数。可微函数的图像在定义域内的每一点上必存在非垂直切线。因此,可微函数的图像是相对光滑的,没有间断点、尖点或任何有垂直切线的点。 一般来说,若X0是函数f定义域上的一点,且f′(X0)有定义,则称f在X0点可微 … WebAug 3, 2024 · A function is differentiable if its derivative exists at each point in its domain.
