F(x) = 15x – 12 + x – 2xf(x) = …​

Jawaban:

f(x) = 15x - 12 + x - 2x

: : : : : = (15x + 1x - 2x) - 12

: : : : = (15 + 1 - 2)x - 12

: : : : = 14x - 12

Diketahui :

f(x) = 15x – 12 + x – 2x

Ditanya :

Nilai f(x)

Jawaban :

f(x) = 15x – 12 + x – 2x

f(x) = (15x + x) – 12 – 2x

f(x) = 16x – 12 – 2x

f(x) = (16x – 2x) – 12

f(x) = 14x – 12
