Section 2.6

The main part of this section that really stood out to me was the compositions of the functions. My college prep teacher gave us a good example of how to do these though.  He told us to consider one of the functions like a donut, and the other function as jelly filling. So if  f(x) is the donut and g(x) is the jelly filling, it'd make it so it's like f(g(x)), and it would make it like a donut.
