Am I rooted? How do I tell?

[deadhead18]

I wanted to revert to os 4.4.3 as I had installed os 5.0.2 and Nexus ran so slowly and kept freezing. As per forum advice I downloaded wugfresh and after some time finally managed to get things right, (I thought). I now have TWRP showing on the Nexus and 'waiting for your device' on the PC. So which option do I select on Nexus? I don't want to mess things up and I have spent two days at this already and I'm missing my Nexus. Help please.
Finally got through the wugfresh procedure after  painful (my fault) process, but having downloaded Titanium to back everything up it says I need to root nexus. Thought I'd done that, but how can I check?

I will try to post a guide tomorrow.

Thank you so much. I never thought I would be become a slave to a piece of kit but I almost feel as though I have cut a hand off not having the Nexus around. You are so kind to help. Please bear in my mind that I'm not that computer savvy; simple for me is best.
