(– 1)^-1(2x+ 1) Does the power series E n=1 converge when x= 0? in No, the series is equiavelent to - 1)^-1 and therefore diverges. n=1 n O No, since the series cannot be evaluated when X = 0. (– 1)"-1 (- 1)n-1 Yes, when X = 0 the series is equivalent to 2 n=1 and since lim = 0 the Divergence Test tells us it converges. (– 1)"-1 Yes, the series is equivalent to E and therefore converges. 1 -ח
