BOB: Class Reflection

So the first week of school has long passed, yet I have still been trying to get into the groove of school and convince my mind to actually absorb information I'm taught in my classes. In my precalc functions class, to tell you the truth, I have been so lost until this past week. I had been struggling and trying to get a grasp on anything that could possibly make sense in my head. We kept going super fast through new information, and as a result I kept getting confused since I was still stuck on the first lecture we had gotten. I understand we use what we learn and just keep adding onto it, so I got frustrated when I couldn't understand a key piece of information, finding the domain of certain functions.

On Thursday last week, something finally clicked in my head and I understood a small portion of what we were doing. I learned that the domain is always all real numbers unless it is a radical or rational function. Radical and rational functions include either x in the denominator of a fraction or a root radical symbol. I believe if you have a radical function, you set what's under the radical equal to or greater than 0. In comparison, I believe if you have a rational function, you set the equation equal to 0. I'm still learning and trying to figure out which method I should use for each function to find the domain.

I know we just started learning about combining functions and finding the domains of those functions. I know how to do the whole combining of functions, and I am just a bit iffy on identifying how to find the domains of those functions. What I really need is a sheet that tells me what each bracket/parenthesis means, how to find the domain of each function, and which method I should use for writing my domains.

I am planning on coming in early and staying after as much as I can until I fully understand what I am doing in this class because I am determined to understand this fully. I feel like I just have a few details in this class that I am not too sure about. Plus, a lot of my friends usually ask me for help on math, and I feel bad if I don't know what I am doing either. I would love to help them out and really just want to understand this so bad!
