Suatu fungsi f dirumuskan sebagai f(x) = 3x – 2 dengan daerah asal adalah A = {–2, –1, 0, 1, 2}. a. Tentukanlah daerah hasil atau range dari fungsi f(x) = 3x –

f(x) = 3x - 2
Daerah asal = A = {-2 , -1 , 0 , 1 , 2}

f(-2) = 3(-2) - 2 = -6 - 2 = -8
f(-1) = 3(-1) - 2 = -5
f(0) = 3.0 - 2 = -2
f(1) = 3.1 - 2 = 1
f(2) = 3.2 - 2 = 4

Daerah hasil dr fungsi f(x) = 3x - 2 :
{-8 , -5 , -2 , 1 , 4}

Domain = A = {-2, -1, 0, 1, 2}
f(x) = 3x - 2

f(-2) = 3(-2) - 2 = -6 - 2 = -8
f(-1) = 3(-1) - 2 = -3 - 2 = -5
f(0) = 3(0) - 2 = 0 - 2 = -2
f(1) = 3(1) - 2 = 3 - 2 = 1
f(2) = 3(2) - 2 = 6 - 2 = 4

Range = {-8, -5, -2, 1, 4}
