WebHowever, if you consider the domain to be all real numbers, it is not continuous. To be continuous at a point (say x=0), the limit as x approaches 0 must equal to the actual function evaluated at 0. The function f(x)=1/x is undefined at 0, since 1/0 is undefined. Therefore there is no way that the f(0) = lim x->0 f(x).

WebWe may be able to choose a domain that makes the function continuous Example: 1/ (x−1) At x=1 we have: 1/ (1−1) = 1/0 = undefined So there is a "discontinuity" at x=1 f (x) = 1/ (x−1) So f (x) = 1/ (x−1) over all Real Numbers is NOT continuous Let's change the domain to x>1 g (x) = 1/ (x−1) for x>1 So g (x) IS continuous WebYes it does, because if f were bounded on [0,s) then by continuity at s (the usual argument) it would be bounded on [0,s+c) for sufficiently small c. Having found the minimal s such that f is unbounded on [0,s), we now hope for a contradiction. By now it is a reflex to apply continuity at s. Then f is bounded on (s-c,s+c) for some suitable c.
