1. 
   /(x) funksiyaning х = 5,04 nuqtadagi taqribiy qiymatini hisoblang:
   

/(x) = x² — 2x

2. 
   Ko‘rsatilgan vaqtdagi tezlik va tezlanishni toping
   

s(t) = 4t² + St — 12, t₀ = 3

3. 
   Berilgan funksiya grafigiga x₀ = 1 abssissali nuqtada o‘tkazilgan urinmani toping. (6 ball)
   

/(x) = 4x² + 5x — 2

4. 
   Berilgan funksiya uchun /'(-), /'(-) sonlami hisoblang.
   

⁴ f(x) = 2stnx — cosx

5.
