Jawaban:
f(x) = 3x² + 2x + 3
f(1) = 3(1)² + 2(1) + 3
= 3 × (1 × 1) + 2(1) + 3
= 3(1) + 2(1) + 3
= (3 × 1) + 2(1) + 3
= 3 + 2(1) + 3
= 3 + (2 × 1) + 3
= 3 + 2 + 3
= 5 + 3
= 8
f(2) = 3(2)² + 2(2) + 3
= 3 × (2 × 2) + 2(2) + 3
= 3(4) + 2(2) + 3
= (3 × 4) + 2(2) + 3
= 12 + 2(2) + 3
= 12 + (2 × 2) + 3
= 12 + 4 + 3
= 16 + 3
= 19
f(2) + f(1)
= 19 + 8
= 27

Semoga membantu.
Jawaban:
27
Penjelasan dengan langkah-langkah:
f(x) = 3x² + 2x + 3
f(2) + f(1)
= (3(2)² + 2(2) + 3) + (3(1)² + 2(1) + 3)
= (3(4) + 4 + 3) + (3 + 2 + 3)
= (12 + 7) + (5 + 3)
= 19 + 8
= 27
