Determine whether f is continuous at 0
WebWhile for x<0 Lim(x---->0) sin(x)/(-x) By applying limit we get anwer -1 Therefore as left hand limit is not equal to right hand limit so f(x) is discontinuous as f(x) =1 at x=0 Any kind of … WebOct 10, 2014 · Explanation: Alternative definition number 1. Let f:X → Y be a function and let (xn) be a sequence in X converging to an element x in X, ie lim (xn) = x ∈ X. Then f is continuous at x iff and only if the sequence of function values converge to the image of x undr f, ie ⇔ lim (f (xn)) = f (x) ∈ Y. Alternative definition number 2.

WebThe next three examples demonstrate how to apply this definition to determine whether a function is continuous at a given point. These examples illustrate situations in which each of the conditions for continuity in the definition succeed or fail. ... If f (x) f (x) is … WebOne is to check the continuity of f (x) at x=3, and the other is to check whether f (x) is differentiable there. First, check that at x=3, f (x) is continuous. It's easy to see that the limit from the left and right sides are both equal to 9, and f (3) = 9. Next, consider differentiability at x=3. This means checking that the limit from the ...
