Ahoj, to, že je funkcia ohraničená môžeš vidieť aj z obrázku. Môžeš si predstaviť, že chceš nakresliť vodorovnú čiaru tak aby bola celá funkcia pod ňou. Dá sa to? Ak áno tak táto čiara funkciu ohraničuje zhora. Podobne by sme to spravili pre ohraničenie zdola, ale chceme nájsť vodorovnú čiaru tak aby bola celá funkcia nad ňou. Čo sa týka otázky , v ktorom bode je ohraničená, nie som si celkom istá čo sa tým myslí.
