I need to find an approximation for (2x-3)/(x+4) centered about 2.So far, I have f(c)=1/6f'(c)=11/6^2f''(c)=-22/6^3f'''(c)=66/6^4etc.So my polynomial is:1/6 + 11(x-2)/6^2 - 22(x-2)^2 /6^3 + 66(x-2)^3 / 6^4 etc.I am having difficulty finding the Kth term.I toyed around with (x-2)^k/6^(k+1) but can't figure out how to get the alternating series portion started because of the two positive integers for k=0 and k=1. Also, I'm not sure how to work in the 11 term that begins at k=1.I would appreciate help with this.
