اختبار الثلاثي الأول السنة 1 ثانوي ج م علوم و تكنولوجيا
التمرين الأول:
b, a, y, x أعداد حقيقية حيث:
X= 4a2 و y= (a-b)2
1- قارن بين العددين A و x حيث A= x – y
2- أحسب A و x من أجل a= -√2 و b= 1
3- عين حصرا للعدد A إذا علمت أن:13.5 ≤ 13.4 ≤ a
و -0.17 ≥-0.18≤ b

التمرينالثاني:
A و B عددان حقيقيان حيث: |2√- A= |x و | B= |x+√2 و x عدد حقيقي
1- عين إشارة Aو B
2- عبر عن العددين A و B باستعمال المسافة.
3- عين العدد الحقيقي x حتى يكون A و B متساويان
4- عين x حتى يكون B اكبر من A
5- إذا كان f(x)= ABحل في R المعادلة f(x) = 0
التمرينالثالث:
· دالة عددية معرفة على المجال [-7; 7] و ( Cf) تمثيلها البياني
إذا علمت أن : دالة فردية متناقصة تماما على [0 ;2] اتحاد [4 ;5] و متزايدة تماما على [2 ;4]اتحاد [5 ;7]
و صور الأعداد 0، 2، 4، 5، 6، 7 هي 2-، 4-، 1- ، 2- ، 0 ، 6 على الترتيب
1- أنشئ جدول تغيرات الدالة f
2- أرسم ( Cf) في معلم متعامد و متجانس
3- استنتج إشارة الدالة f على المجال [[-7;7
