11. [8 points] Find the Taylor Series of the function f (x) = = centered at a = -3 using the definition of a Taylor Series. (To be clear, you MUST show your work finding derivatives, etc. Do NOT just use the table as a starting point.)12. [8 points] Use either the Alternating Series Test or the Test for Divergence to determine if the series converges or diverges. X(-1)n+1 Vn 2n + 3 n= 1
