Functions Unit B.O.B....

   Overall, I feel that this unit challenged me a lot, and definitely confused me at some times.  The major thing that really hindered my understanding the material was not knowing the basic rules of when fractions could be reduced.  The major rule that I kept forgetting about was the rule of what could “cancel out” in fractions.  This rule stated that numerators and denominators do not cancel out if the term is being added, subtracted or multiplied by another.  For example, if the equation is (x+1)/x, that is the simplest form, and it cannot be reduced.  However, if the fraction is (2x+4)/(x+4), then it can be reduced to just x+4.  For some reason, I found this very hard to remember so I just went crazy and started cancelling out everything in a fraction that looked similar.  This made most of the questions seem easier to solve, but obviously I got all of them wrong.  With that said, it sounds cliché, but I truly feel like I will learn from my mistakes and really think about what I am cancelling out.  Lastly, I learned that I cannot take my previous knowledge for granted, because it can save my life.
