What does Descartes' rule of signs tell us about the number of positive real zeros and the number of negative real zeros of the function? \( \qquad \mathrm{x})=\mathrm{x}^{4}-7 \mathrm{x}^{2}+19 \mathrm{x}-23 \) The possible number of positive real zeros is \( \square \), and the possible number of negative real zeros is \( \square \).
