Function is not differentiable for :
WebHere is a proof that the Cantor function f is not differentiable at non-endpoints of the Cantor set. Let C 0 = [ 0, 1], and let C n be constructed from C n − 1 by removing an … WebIn calculus, it is commonly taught that differentiable functions are always continuous, but also, all of the "common" continuous functions given, such as f ( x) = x 2, f ( x) = e x, f ( x) = x s i n ( x) etc. are also differentiable. This leads to the false assumption that continuity also implies differentiability, at least in "most" cases.

WebAssume f is a continuous function which is differentiable on the interval (1, 9). If f (9) = 0 and f ′ (x) ≥ 8 for all x, what is the largest possible value of f (1)? Justify your solution. Solution: Since f is continuous everywhere and differentiable on (1, 9), then the Mean Value Theorem states that there exists c ∈ (1, 9) such that f ... WebEvery differentiable function is continuous, but there are some continuous functions that are not differentiable. Show more 1.3M views Limits at Infinity (Rational square-root …
WebQuestion: Determine if the piecewise-defined function is differentiable at the origin. f(x)={4x+tanx,x2,x≥0x<0 Select the correct choice below and, if necessary, fill in the answer boxes in your choice. A. The function is not differentiable at the origin because limh→0−hf(0+h)−f(0)= and limh→0+hf(0+h)−f(0)= (Type integers or simplified fractions.) WebA differentiable function is always continuous, but the inverse is not necessarily true. A derivative is a shared value of 2 limits (in the definition: the limit for h>0 and h<0), and this is a point about limits that you may already know that answers your question.
WebWe can say that f is not differentiable for any value of x where a tangent cannot 'exist' or the tangent exists but is vertical (vertical line has undefined slope, hence undefined derivative). Below are graphs of … WebFind all points where f ( x) fails to be differentiable. Justify your answer f ( x) = x − 1 I am confused with continuity of it and cannot turn it into piecewise function and finding the limit of it at the points by piecewise function Sorry for bad explanation :- ( limits derivatives continuity Share Cite Follow edited Oct 26, 2013 at 18:26

WebSep 6, 2024 · I am curious to know whether it is possible to say soemthing like this: "function f is differentiable until point x=5 but for values x>5 it is no longer differentiable". (I know that you can achieve this with functions like f ( x) = x q p, p, q ∈ N at point 0 but that is not what I am looking for.)

However, the mean value theorem can be applied to your second case since f is continuous on [ 0, 2] and differentiable on ( 0, 2). Check precisely the requirements of the MVT. The differentiability on ( 0, 2) follows since the formula by Dr. Sonnhard Graubner in the other answer holds. out-binWebJun 8, 2024 · b) This function transforms the input values between 0 and 1 and centered at 0.5 ie. not zero centered. c) The function is monotonic and differentiable.
