WebMar 10, 2024 · A differentiable function must be continuous. However, the reverse is not necessarily true. 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. WebJul 12, 2024 · A function can be continuous at a point, but not be differentiable there. In particular, a function f is not differentiable at x = a if the graph has a sharp corner (or cusp) at the point (a, f (a)). If f is differentiable at x = a, then f is locally linear at x = a.

WebStudying about the continuity of a function is really important in calculus as a function cannot be differentiable unless it is continuous. Let us study more about the continuity of a function by knowing the definition of a … WebSince f is differentiable over I, f must be continuous over I. Suppose f(x) is not constant for all x in I. Then there exist a, b ∈ I, where a ≠ b and f(a) ≠ f(b). Choose the notation so that a < b. Therefore, f(b) − f(a) b − a ≠ 0. Since f is a differentiable function, by the Mean Value Theorem, there exists c ∈ (a, b) such that WebExpert Answer.
