Taylor series of f(x)=x-x^3, a=-2
with radius of convergence and interval of convergence

Polynomials can't be expressed as series because they're not infinitely differentiable. Just do the algebra to compensate for the difference between x - x³ and (x+2) - (x+2)³ since it wants it centered at a = - 2.
