\noindent {\bf Problem statement} The graphs of two functions, $f(x)$
and $f(x)$, are shown below. Answer the following questions as well as
possible by considering these graphs.

\medskip

\noindent a) What is the largest possible radius of convergence of a
power series centered at 0 whose sum is $f(x)$?

\medskip

\noindent b) What is the largest possible radius of convergence of a
power series centered at 0 whose sum is $g(x)$?
