Answer 1

Diketahui :

f(x) = 3x + 2

Ditanya :

Nilai f(2) + f(1) = ...?

Dijawab :

f(x) = 3x + 2

f(2) = 3x + 2

f(2) = 3(2) + 2

f(2) = 3 × 2 + 2

f(2) = 2 + 2 + 2 + 2

f(2) = 4 + 2 + 2

f(2) = 6 + 2

f(2) = 8

f(x) = 3x + 2

f(1) = 3(1) + 2

f(1) = 3 × 1 + 2

f(1) = 3 + 2

f(1) = 5

Hasil nya

= f(2) + f(1)

= 8 + 5

= 13 √

Keterangan :

→ hasil dari f(2) + f(1) adalah 13

semoga membantu

Answer 2

Penjelasan dengan langkah-langkah:

f(2) = 3.2 + 2

f(2) = 6 + 2

f(2) = 8

f(1) = 3.1 + 2

f(1) = 3 + 2

f(1) = 5

= f(2) + f(1)

= 8 + 5

= 13
