Diketahui rumus fungsi f(x) = 2x + 3. Tentukan nilai f(1) + f(2) !​

Answer 1

Jawaban:

12

Penjelasan dengan langkah-langkah:

f(x) = 2x + 3

f(1) + f(2)

= (2(1) + 3) + (2(2) + 3)

= 5 + (4 + 3)

= 5 + 7

= 12

Answer 2

Nilai f(1)

• f(x) = 2x + 3
• f(1) = 2(1) + 3
• f(1) = ( 2 × 1 ) + 3
• f(1) = 2 + 3
• f(1) = 5

Nilai f(2)

• f(x) = 2x + 3
• f(2) = 2(2) + 3
• f(2) = ( 2 × 2 ) + 3
• f(2) = 4 + 3
• f(2) = 7

Maka

Nilai f(1) + f(2)

• f(1) + f(2)
• 5 + 7
• = 12

Jadi, Nilai dari f(1) + f(2) adalah 12.
