Depends on how long it stayed that warm. Yeast stored at warm temps will use up its reserves much more quickly. If it was at those temps a few days the starter would probably be enough to build you up plenty of viable cells. If it was at those temps a few weeks, I'd save yourself the anxiety and just spend the money on some new yeast.
If you do attempt to use it, pay particular attention to the sights, smells and tastes of your starter. If there are significant issues, they will stick out as "different" from your usual starters.
