Hi and welcome to the forums!
Looks like you have a dracaena Janet Craig. They are very easy plants. I have found that when they get too tall or leggy, I have cut them back and rooted the top part, or simply put the cut piece back into the soil after removing the bottom leaves. The top of the original plant will put out new growth on 2 sides of the tip.
Many many years ago when I lived in Reno, a local library severly cut back their very tall dracaenas and I took 3 pieces home. I had some lovely free and large plants!
I just read this online about dracaenas, and find it very interesting, as my daughter is allergic to formaldehyde:
The temperature requirements for Janet Craig is a comfortable 75 degrees and the water requirements are low. Dracaenas are one of the plants used in the NASA Clean Air Study and has shown to help remove Formaldehyde.
