Salut, sunt in clasa 8 si astazi ne-a predat dirigintele meu (este si prof de mate) intervalele de numere reale si ne-a predat doar teoria,dar nu ne-a explicat cum se rezolva in practica... si Am nevoie sa-mi raspundeti :
Noteaza multimile urmatoare folosind simboluri:
1 exercitiu: interval inchis de la - radical 5 la radical 7
interval inchis de la -3 la 2radical5
interval inchis de la -infinit la 10
interval inchis de la 3 la +infinit..

2. reprezinta pe axa multimea nr. reale x care satica relatiile indicate:
a) x>sau egal cu 2; b) x <sau egal -5.
c) x >4
d) x < -3,5
e) x<sau egal cu 0
f) x > 0.
Asta e tot
