For (e^x-1) / x, is x the exponent or x - 1? I just wanted to double check that, anyways, I had a question I believe to be identical to this one on my calc final last year..

If it is only x, then to solve this, use the Taylor Polynomial for e^x centered at x = 0 which you should have memorized, then subtract one from it and then divide every term by x.
