Justify your response with an explanation or counterexample. 161) f(t) = 2 et − e − t is continuous everywhere. Answer: 162) If the left- and right-hand limits of f(x) as x → a exist and are equal, then f cannot be discontinuous at x = a.

WebSteps for Determining if a Function is Continuous at a Point Within An Interval. Step 1: Identify the given function f (x) and the interval (a,b). Step 2: If the given function is a rational ... WebTo understand continuity, it helps to see how a function can fail to be continuous. All of the important functions used in calculus and analysis are continuous except at isolated points. Such points are called points of discontinuity. There are several types. Let’s begin by first recalling the definition of continuity (cf. book, p. 75).

WebNov 16, 2024 · Using only Properties 1- 9 from the Limit Properties section, one-sided limit properties (if needed) and the definition of continuity determine if the following function is continuous or discontinuous at (a) x = −1 x = − 1, (b) x = 0 x = 0, (c) x = 3 x = 3? f (x) = 4x+5 9 −3x f ( x) = 4 x + 5 9 − 3 x Show All Solutions Hide All Solutions WebSorted by: 2. Continuity of a function is defined if it is continuous in the entire domain , such that for every a , f ( a) = lim x → a f ( x) should exist . Now for g ( x) you can verify … WebFeb 22, 2024 · f is differentiable, meaning f ′ ( c) exists, then f is continuous at c. Hence, differentiability is when the slope of the tangent line equals the limit of the function at a given point. This directly suggests that for a function to be differentiable, it must be continuous, and its derivative must be continuous as well. hideaway bamberg
