(a) (10pts) Let f(x)=x2+11. Explain why f(x) is continuous and positive on the interval [0,∞). Then show that f(x) is decreasing on (0,∞). (b) (12 pts) Using the Integral Test and your answer to part (a), determine whether the series n=1∑∞n2+11 is convergent or divergent. (Recall that the antiderivative of f(x)=x2+11 is arctanx.)
