Answer 1

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

Answer 2

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
