How can a function be differentiable

Web5 de set. de 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. WebFor example, the function f ( x) = 1 x only makes sense for values of x that are not equal to zero. Its domain is the set { x ∈ R: x ≠ 0 }. In other words, it's the set of all real numbers that are not equal to zero. So, a function is differentiable if its derivative exists for every x …
