WebJul 5, 2013 · The result that every continuous function is bounded on a closed interval is itself another property of continuous functions which can't be proved without using completeness of real number system. I have presented various proofs of these properties of continuous function here.

WebJun 20, 2024 · It is worthwhile to give another proof for Riemann integrability of functions which are continuous on a closed interval. The proof below is taken from Calculus by Spivak and I must say it is novel enough. It does not make use of uniform continuity bur rather invokes mean value theorem for derivatives. WebThe function is continuous because lim x→−1 + f(x) and lim x→7 − f(x) both exist. The function is continuous because lim x →0 − f ( x ) = lim x →0 + f ( x ) = f (0) = 9. The …
WebOct 21, 2015 · (In fact, for any finite, closed interval [ a, b] and continuous function f, [ a, b] is compact and so f ( [ a, b]) is compact and nonempty and hence not open. So, for any continuous f and interval I satisfying the criteria, we must have that I is infinite, which here I mean to include half-infinite.)
