Week 5 Muddiest Point

I have been struggling with the concepts that were featured in the Applied Functions worksheet that was given to us in class this week.  It just doesn't seem to be clicking in my head just yet.  I am hoping that I will be able to understand it more with some more practice at home and in class next week!  On another note, I like the idea of being called on randomly in class because knowing that there is a chance of being called on gives me the motivation I need to work through a challenging problem the best that I can, and if I'm wrong I will be able to remember my mistake and try not to make it again.
