Question 2

Using the known geometric series representation   = xⁿ,  valid for  -1 < x < 1, find a power series representation for  f(x) = ln ((1+x)²)  in powers of  x. On what interval does the series converge to  f(x)?
◦ f(x) = ,  for  -1 ≤ x ≤ 1
◦ f(x) = ,  for  -1 < x < 1
◦ f(x) =  ,  for  -1 < x ≤ 1
◦ f(x) = ,  for  -1 ≤ x < 1
◦ f(x) =  ,  for  -1 < x ≤ 1
