Find a power series representation of the function:

and determine the interval of convergence.

Here is my work:

Ok, I found my interval of convergence:

-1 < x <1

But to test each end point, where do I plug those into? Into the series ?

the end points are x=1 and x=-1, so you must change x by those values in the series and determine its convergence
