Let f(x)=∑n=0∞anxnf(x) = \sum_{n=0}^{\infty} a_n x^nf(x)=∑n=0∞​an​xn be a power series with a radius of convergence R=2R=2R=2. Consider the function g(x)=∑n=0∞an2xng(x) = \sum_{n=0}^{\infty} a_n^2 x^ng(x)=∑n=0∞​an2​xn. Which of the following statements about the radius of convergence RgR_gRg​ of g(x)g(x)g(x) is correct?
