Determine the graphs for f' and f'' for each function y=f(x)

2. Relevant equations

y=(2^x)/((x^2)-1)

3. The attempt at a solution

I've been out of class for a while, and our textbook is hardly clear as to using nDeriv. I've tried entering in both y1=nDeriv((2^x)/((x^2)-1), x) and y1=nDeriv((2^x)/((x^2)-1), x, x) to graph f', but both result in a few seconds of a graph before spitting out err:argument (using a TI-83+). What am I doing wrong here?
