WebProblem-Solving Strategy: Determining Continuity at a Point Check to see if f (a) f ( a) is defined. If f (a) f ( a) is undefined, we need go no further. The function is not continuous at a a. If f (a) f ( a) is defined, continue to step 2. Compute lim x→af (x) lim x → a f ( x). WebSep 5, 2024 · A function f: D → R is called uniformly continuous on D if for any ε > 0, there exists δ > 0 such that if u, v ∈ D and u − v < δ, then f(u) − f(v) < ε. Example 3.5.1 Any constant function f: D → R, is uniformly continuous on its domain. Solution Indeed, given ε > 0, f(u) − f(v) = 0 < ε for all u, v ∈ D regardless of the choice of δ. pasat esercizi https://telefoniastar.com

WebCheck the continuity of the function f given by f (x) = 3x + 2 at x = 1. Solution: Given, f (x) = 3x + 2 Substituting x = 1 in f (x), f (1) = 3 (1) + 2 = 3 + 2 = 5 Thus, the function is defined at the given point x = 1 and its value is 5. Now, we have to find the limit of the function at x = 1. WebIf a function f is only defined over a closed interval [c,d] then we say the function is continuous at c if limit(x->c+, f(x)) = f(c).
