Determine whether f is continuous at 0
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 ...

WebBut if the formal definition of whether a function is continuous is lim_x->c f(c) = f(c), and you have a graph with a jump discontinuity at both ends of a point... Example f(x)={x if 0 < x < 2, 5 - x if 2 < x < 4} Since both the limit and f(x) are undefined at x = 2, would the formal definition be proving the graph continuous?? 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 …
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 … WebLet f be a function that is continuous on an interval I. Suppose c is a critical number of f and (a, b) is an open interval in I containing c. Prove that if f ′ (x) f^{\\prime}(x) f ′ (x) has the same sign on both sides of c, then f(c) is neither a local maximum value nor a …
WebBecause you can't take the square root of a negative number, sqrt (x) doesn't exist when x<0. Since the function does not exist for that region, it cannot be continuous. In this video, we're looking at whether functions are continuous across all real numbers, which is why sqrt (x) is described simply as "not continuous;" the region we're ...
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.
