f(x) = 4x³ + x² + 4x - 5
---
f(1) = 4(1)³ + 1² + 4(1) - 5
f(1) = 4(1) + 1 + 4 - 5
f(1) = 4
---
f(2) = 4(2)³ + 2² + 4(2) - 5
f(2) = 4(8) + 4 + 8 - 5
f(2) = 32 + 7
f(2) = 39
---
f(3) = 4(3)³ + 3² + 4(3) - 5
f(3) = 4(27) + 9 + 12 - 5
f(3) = 108 + 16

Verified answer
Jawaban:
f(1) = 4
f(2) = 39
f(3) = 124
Penjelasan dengan langkah-langkah:
f(x) = 4x³ + x² + 4x - 5
f(1) = 4(1)³ + 1² + 4(1) - 5
= 4 + 1 + 4 - 5
= 5 + 4 - 5
= 4
f(2) = 4(2)³ + 2² + 4(2) - 5
= 4(8) + 4 + 8 - 5
= 32 + 4 + 8 - 5
= 36 + 8 - 5
= 44 - 5
= 39
f(3) = 4(3)³ + 3² + 4(3) - 5
= 4(27) + 9 + 12 - 5
= 108 + 9 + 12 - 5
= 117 + 12 - 5
= 129 - 5
= 124
