Jawaban Terkonfirmasi
Quick Tips!
⇒ |f(x)| = a, maka f(x) = a atau f(x) = – a
=================================
Tentukan nilai x dari persamaan nilai mutlak |4x – 1| = 7
|4x – 1| = 7
4x – 1 = 7
4x = 7 + 1
4x = 8
x = 2
==================
4x – 1 = – 7
4x = – 7 + 1
4x = – 6
x = – 6/4
x = – 3/2
Maka, nilai x haruslah – 3/2 atau 2
