The function is defined by the power series
f(x) = 1 + (x+1)+ (x + 1)² ++ (x + 1)² + ... =
-=[(x+1)"
n=0
(x+1)*. -/<x+1 <1
(22x20
for all real numbers x for which the series converges.
(a) Find the interval of convergence of the power series for f. Justify your answer.
(b) The power series above is the Taylor series for f about x = -1. Find the sum of the series for f.
(c) Let g be the function defined by g(x) = f(t) dt. Find the value of g(-2), if it exists, or explain
why g(-1) cannot be determined.
(d) Leth be the function defined by h(x) = f(x²-1). Find the first three nonzero terms and the general
term of the Taylor series for h about x = 0, and find the value of h
8 h (2).
