Oraliq nazorat ishi – 1.
I-variant.
1. Berilgan logarifmik funksiya grafigini yasang.
y=log4 x
2. Berilgan funksiyaga teskari funksiyani toping.
a) y=3x-1 b) y=6x
3. Sodda logarifmik tenglamani yeching.
log7x=3
log2(5+x)=3
4. Masala .
AB kesmaning oxirlaridan va uning M o’rtasidan biror tekislikni A1,B1,M1
kesuvchi parallel to’g’ri chiziqlar o’tkazilgan. Agar AB kesma tekislikni
kesib o’tmasa va AA1=5sm, BB1=7sm bo’lsa, MM1 ni toping.
II-variant.
1. Berilgan logarifmik funksiya grafigini yasang.
y=log x
2. Berilgan funksiyaga teskari funksiyani toping.
a) y=5x-4 b) y=log7x
3. Sodda logarifmik tenglamani yeching.
a) log4 x=5
b) log3(x+2)=4
4. Masala.
AB,AC va AD to’g’ri chiziqlar juft-juft perpendikulyar. Bunda AB=3sm,
BC=7sm, AD=1,5 sm bo’lsa, CD kesmani toping.
