Jawaban:

R = {-16 , -13 , -10 , -7 , -4}

Penjelasan dengan langkah-langkah:

Domain = -2

-2 = x + 2

x = -4

f(-4 + 2) = 3(-4) - 4

f(-2) = -12 - 4

f(-2) = -16

Domain = -1

-1 = x + 2

x = -3

f(-3 + 2) = 3(-3) - 4

f(-1) = -9 - 4

f(-1) = -13

Domain = 0

0 = x + 2

x = -2

f(-2 + 2) = 3(-2) - 4

f(0) = -6 - 4

f(0) = -10

Domain = 1

1 = x + 2

x = -1

f(-1 + 2) = 3(-1) - 4

f(1) = -3 - 4

f(1) = -7

Domain = 2

2 = x + 2

x = 0

f(0 + 2) = 3(0) - 4

f(2) = -4

Jadi, daerah hasilnya adalah {-16 , -13 , -10 , -7 , -4}
