Since the first exam we have learned Rational Functions, Exponential Functions, Composition of Functions and Inverse Functions and Logarithms. What I found interesting there is a natural number called “e” (2.718). Ironically it is not natural since it’s an irrational number. “e” is often the base of the Natural Logarithms. The number e can be found in compound interest for loans and investment and etc. What I found difficult was Composition of Functions and Inverse Functions. Being able to decompose a composite function into two or more simpler functions. There many more things we will learn in this class and each topic was interesting in its own way but some were more challenging than others. What did you find difficult and how did you overcome that challenge?
