I seem to have a lot of trouble with ranges of combined functions. I must be missing something or not understanding something. Domains don't give me a problem but when it comes to ranges I usually end up having to resort to a graph and plotting points etc and I'm wondering if there is a better way. I'm wondering if someone can guide me through the thought process of finding the range for the one given below.
Domain: I found the range as: Even if that's the range, I think the process I use to find the range is not correct so I'm wondering about other people's way of finding the range. Also, is there a common way to find ranges of most combined functions or is it usually different.
