Materi : Konsep Mutlak
|x² - 3| < 1
x² - 3 < 1
x² < 1 + 3
x² < 4
x < √4
[ x < 2 ]
- x² + 3 < 1
x² > 3 - 1
x² > 2
[ x > √2 ]
Maka HP = { x | x < 2 atau x > √2 }
Semoga bisa membantu

Materi : Konsep Mutlak
|x² - 3| < 1
(1) f(x) < 1
x² - 3 < 1
x² < 1 + 3
x² < 4
x < √4
[ x < 2 ]
(2) - f(x) < 1
- x² + 3 < 1
x² > 3 - 1
x² > 2
[ x > √2 ]
Maka HP = { x | x < 2 atau x > √2 }
Semoga bisa membantu
