| Nov 30, 2019 at 16:06 | comment | added | Martin Sleziak | I will just point out that such functions can be obtained even without AC, some such examples can be found in this post on MathOverflow: Function with range equal to whole reals on every open set and also in several posts on Mathematics such as this one and other questions linked there. Functions with this property are sometimes called strongly Darboux. | |
