changing the extent

[TonyRopson]

hi,
I am doing a buffer query this piece of code is zooming into the feature. 

if (featholding.length > 0 && featholding.length == parnums.length - 1) {
                map.setExtent(esri.graphicsExtent(featholding[0].features),true);
         
            }

I would like to change the extent a bit so the end user can see more of the area surrounding this feature.  How would I go about changing the extent to do this?
Thanks

map.setExtent(esri.graphicsExtent(featholding[0].features).expand(1.2),true);
