Jika f(x) = 3x + 2. Nilai f(2) + f(-1) = ...​

Answer 1

f(2) + f(-1)

( 3x + 2 ) + ( 3x + 2 )

( 3 (2) + 2 ) + ( 3(-1) + 2 )

( 6 + 2 ) + ( -3 + 2 )

8 + ( -1 )

8 - 1

7

Answer 2

: - Fungsi

Penjelasan dengan langkah-langkah:

Ket.

• Nilai f(x) = 3x + 2

---

• Nilai f(2) ?

f(x) = 3(x) + 2

f(2) = 3(2) + 2

f(2) = 6 + 2

f(2) = 8

• Nilai f(1) ?

f(x) = 3(x) + 2

f(-1) = 3(-1) + 2

f(-1) = (-3) + 2

f(-1) = (-1)

• Maka Nilai f(2) + f(-1)

= nilai f(2) + nilai f(-1)

= 8 + ( -1 )

= 7
