Answer:
a) we know that this is convergent.
b) we know that this might not converge.
Step-by-step explanation:
Given the
is convergent
Therefore,
(a)
The power series
has radius of convergence at least as big as 8. So we definitely know it converges for all x satisfying -8<x≤8. In particular for x = -3
∴
is convergent.
(b)
-8 could be right on the edge of the interval of convergence, and so might not converge
