WebBolzano's proof consisted of showing that a continuous function on a closed interval was bounded, and then showing that the function attained a maximum and a minimum value. Both proofs involved what is known today as the Bolzano–Weierstrass theorem. [1] The result was also discovered later by Weierstrass in 1860. [citation needed] WebTheorem.

A = { x: a < x < b and f < 0 ∈ [ a, x] } A ≠ ∅ ∃ δ: a ≤ x < a + δ ⇒ x ∈ A b is an upper bound and ∃ δ: b − δ < x ≤ b and x is another upper bound of A.
