1. Gegeben ist die quadratische Funktion f(x) = x^2 + px + q.
2. Die Nullstellen einer Funktion finden wir, indem wir f(x) = 0 setzen: x^2 + px + q = 0.
3. Die quadratische Gleichung hat reale Lösungen, wenn die Diskriminante \Delta = p^2 - 4q \geq 0 ist.
4. Daher existieren reelle Nullstellen der Funktion f(x) für die Werte von x, wenn p^2 - 4q \geq 0 gilt.
