Dominant ninth chords take the place of a plain dominant seventh in blues, funk, soul and jazz. As the V9 they resolve just like a V7 does, only with more colour on the way.
E9 is E7 with a major ninth on top, so it keeps the dominant pull of the tritone. It differs from Emaj9 in the seventh, minor rather than major, and from Eadd9, which has no seventh at all. In E7♭9 and E7♯9 the same ninth is moved a half step down or up.
A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.
