Specifically this lens

Pentax Autofocus 70-300 F4-5.6 SIGMA DL MACRO (58) WITH CAPS 35MM SLR AUTO FOCUS ZOOM TELEPHOTO LENS - KEH.com

Will it work with Autofocus on my K-x ?

I believe mine is the same lens and yes, it does.

I used to own this lens upto 2007. It used to autofocus fine on my K100D. Suffered from zoom creep though, as is to be expected of a consumer grade long zoom.
