WebEarlier, we showed that f is discontinuous at 3 because lim x → 3 f (x) lim x → 3 f (x) does not exist. However, since lim x → 3 − f (x) = −5 lim x → 3 − f (x) = −5 and lim x → 3 + f … http://websites.umich.edu/~kfid/MYPUBS/Fidkowski_Oliver_Lu_Darmofal_2005.pdf
WebThe function f is discontinuous at x = 0 because lim f(x) does not exist. x 0 The function f is discontinuous at x = 0 because lim f(x) exists, but this limit is not equal to fo). O The function f is continuous everywhere because the three conditions for continuity are satisfied for all values of x.

WebSep 28, 2024 · Since f ( x) is not defined at 0, by definition it is discontinuous. You don't need to use intervals to demonstrate this. If, instead, you are trying to show that this is not a removable discontinuity, you can use a similar proof structure to what you've started. That is, you can show that if we define f ( 0) = c for some c ∈ R, f is still ... Webbut f(0) does not even exist. Even if f(0) is defined to be say 1, or 0, the derivative f′(0) does not exist. Remember the important little theorem (Simmons p. 75) (3) f(x) differentiable at a ⇒ f(x) continuous at a or to put it contrapositively, f(x) discontinuous at a ⇒ f(x) not differentiable at a
WebAnswer (1 of 3): Yes. Define a function, f, over the set of positive real numbers like this: f(x) = x when x is rational and = -x when x is irrational. This certainly is discontinuous. …
