| 3x−3 | ||
Wyznacz zbiór wartości funkcji f(x)= | ||
| |−x+1| |
| 3x−3 | ||
f(x) = | ||
| |−x+1| |
| 3x−3 | 3(x−1) | |||
f(x) = | = | |||
| |−x+1| | |x−1| |
| 3(x−1) | 3(x−1) | 3(x−1) | ||||
f(x) = | = | = | ||||
| |−x+1| | |−(−x+1)| | |x−1| |
| 3(x−1) | ||
dla x∊(−∞;1) masz f(x) = | = −3 | |
| −(x−1) |
| 3(x−1) | ||
dla x∊(1;+∞) masz f(x) = | = 3 | |
| x−1 |
generalnie to pierwszy raz widze coś takiego 
jest inny sposób?
