Fungsi f : x ➡4x - 2, x = { -1, 0, 1, 2, 3 }. Daerah hasil fungsi f adalah

f(x) = 4x - 2

daerah asal
x = {-1, 0, 1, 2, 3}

f(-1) = 4(-1) - 2 = -4 - 2 = -6
f(0) = 4(0) - 2 = 0 - 2 = -2
f(1) = 4(1) - 2 = 4 - 2 = 2
f(2) = 4(2) - 2 = 8 - 2 = 6
f(3) = 4(3) - 2 = 12 - 2 = 10

daerah hasil {-6, -2, 2, 6, 10}
