Use Descartes's Rule of Signs to determine the possible number of negative real zeros for the given function.
So far I have this:
1 negative real root.

Follow Math Help Forum on Facebook and Google+
g(x) has -+-+ That's 3, so 3 or 1 positive.
g(-x) has +--+ That's 2, so 2 or 0 negative.
ALL the negative powers change sign for g(-x). You missed the term.
