Webis continuous at 0, and differentiable everywhere except at 0. You can still apply Rolle's theorem to this function on say the interval ( 0, 1 π). If the statement of Rolle's theorem required the use of the closed interval, then you could not apply it to this function.

Continuity over an interval (practice) Khan Academy

WebJan 25, 2024 · Continuity: Conditions 1. In an open interval \ ( (a, b),\) a function \ (f\) is said to be continuous if it is continuous at all points in the interval. 2. In a closed interval \ ( [a,b],\) a function \ (f\) is said to be … WebDec 6, 2024 · 2 Answers. Yes, that is correct. In fact, assuming that the domain of f is ( a, b): F: [ a, b] R x ↦ { lim x → a + f ( x) if x = a f ( x) if x ∈ ( a, b) lim x → b − f ( x) if x = b. … WebSure it can, a simple example is the function f ( x) = x on the interval ( 0, 1).
