Jawaban:
c. -11 ≤ f(x) ≤ 17
Penjelasan dengan langkah-langkah:
Daerah asal : {-1, 0, 1, 2, 3, 4, 5}
f(x) = 4x - 3
f(-2) = 4(-2) - 3 = -8 - 3 = -11
f(-1) = 4(-1) - 3 = -4 - 3 = -7
f(0) = 4(0) - 3 = 0 - 3 = -3
f(1) = 4(1) - 3 = 4 - 3 = 1
f(2) = 4(2) - 3 = 8 - 3 = 5
f(3) = 4(3) - 3 = 12 - 3 = 9
f(4) = 4(4) - 3 = 16 - 3 = 13
f(5) = 4(5) - 3 = 20 - 3 = 17
Jadi, jawabannya adalah C.
