I found a variety called 'Yellow Coast' that looks a lot like yours. While I searched I came across several sites that had pictures and names so mixed up it was unreal. Like a picture of 'Massangeana' identified as 'Warneckei'. Closely related, yes. Similar enough to confuse, NOT!! I feel so sorry for people who are just learning. I realize a Dracaena is pretty much a Dracaena, but it really makes you wonder just how mixed up are important things?

It's definitely a Corn Plant (Dracaena fragrans) but if the plant wasn't labeled when you acquired it, it's likely impossible to know an exact cultivar name since so many look quite similar.
