CHIZIQLI FUNKSIY

FUNKSIYA TUSHUNCHASI

  1. K oordinatalari: 1) (0; 4); 2) (3; 0); 3) (4; 4); 4) (5; 9); 5) (3; 1);
    6) (—1; 9); 7) (4; 10) bo'lgan nuqtalaming qaysilari y= x2— x + 4 funksiya grafigiga tegishli, qaysilari tegishli emas?



  2. Koordinata tekisligida A (6;2), B (3;-1), C (2;4,5), D (-3,5;-3 ,5 )
    nuqtalar berilgan. Bu nuqtalarga Ox o ‘qqa nisbatan sim m etrik nuqtalar yasang va ularning koordinatalarini yozing. Qanday xulosaga kelish mumkin?

  3. Koordinata tekisligida A (5; 1),B (4;-1,5), C (-3; 4), D (-2,5;-4) nuqtalar berilgan. Bu nuqtalarga Oy o ‘qqa nisbatan simmetrik nuqtalar yasang va ularning koordinatalarini yozing. Qanday xulosaga kelish mumkin? Xulosangizni daftaringizga yozib qo‘ying.

  4. Uchlari A (0; —3), B (—2; 3), C (5; 2) nuqtalarda bodgan uchburchak yasang. Uchburchak tomonlarining Ox, Oy o ‘qlar bilan kesishish nuqtalari koordinatalarini toping.

  5. Uchlari A (-3;-4), B (-3; 4), C(3; 2), D (3;-2) nuqtalarda bodgan to'rtburchak yasang. To‘rtburchak tomonlarining koordinata o‘qlari bilan kesishish nuqtalarining koordinatalarini toping.

  6. U chlari A (5; 3), B (—2; 3), C (—2; 2), D (5; —2) nuqtalarda bodgan ABCD to ‘g ‘ri to 'rtb u rc h a k yasang. U ning perimetri va yuzini hisoblang.

  7. Koordinata tekisligida A (—8; 3), B (1; 3), C(1; —2) nuqtalarni belgilang. To‘rtinchi nuqtani — D nuqtani shunday yasangki, natijada ABCD to ‘g‘ri to‘rtburchak hosil bodsin. Uning perimetri va yuzini hisoblang.
