1. The problem statement, all variables and given/known data http://imgur.com/1aOFPI7 PART 2 2. Relevant equations Taylor series form 3. The attempt at a solution My thought process is that the answer is 3 because using the geometric series equation (1st term)/(1-R) then you can get the sum. In this case R would be x+2 where x is -2 so 0. 1st term is 3/1 so the answer would be 3. I feel like this isn't what I'm supposed to do as it's saying the power series is the taylor series of some function, f but I have no idea how I could find a sum for that.
