I think the spacing looks fine without the "\text{ }" pieces strewn in. The one place you may want to use extra spacing is between the comma and f(x1), but I would use either \enspace or \quad to enact the spacing instead. Those commands are specifically for that purpose. And again, you may want to get rid of the line altogether if you end up just listing the two points in the initial statement.
