Problem

Consider the power series P(x)=∑n=1∞n!nn (x−2)n.P(x)=\sum_{n=1}^{\infty}\frac{n!}{n^{n}}\,(x-2)^{n}. Respond to each of the following prompts. (1) Determine the radius of convergence RR of P(x)P(x). (2) Identify all real numbers xx for which the series converges absolutely. (3) Analyze the behavior of the series at each endpoint of the interval found in part (b) and state the complete interval of convergence, justifying your conclusions.
