tolong jawab yaak entar sore dikumpull..pake cara yak entar aku kasih lagi soalnya tapi pake cara juga
Diketahui f(x) = 2x – 4
* jika x = – 3
pakai substitusi, maka f(x) = 2 . (-3) – 4 = -6 – 4 = -10
* jika x = -2
f(x) = 2 . (-2) – 4 = -4 – 4 = -8
*jika x = -1
f(x) = 2.(-1) – 4 = -2 -4 = -6
*jika x = 0
f(x) = 2.0 – 4 = -4
*jika x = 1
f(x) = 2.1 – 4 = -2
*jika x = 2
f(x) = 2.2 – 4 = 0
*jika x = 3
f(x) = 2.3 – 4 = 2
*jika x = 4
f(x) = 2.4 – 4 = 4
