f(x) = | zał. |x| ≠ 2 czyli x ≠ 2 i x ≠ −2 | |
|x| − 2 |
−x | ||
1. x ∊ (−∞; 0) ⇒ f(x) = | ale nie wiem jak doprowadzić to do wzoru funkcji | |
−x + 2 |
−x | (−x+2)−2 | ||
= | |||
−x + 2 | −x+2 |
−2 | ||
Czyli powinno wyjść ostatecznie | + 1? | |
x + 2 |
−x | −x | x | |||
= | = | ||||
−x+2 | −(x−2) | x−2 |
x | x−2+2 | x−2 | 2 | 2 | |||||

x−2 | x−2 | x−2 | x−2 | x−2 |
