Question

Q

f(x + a) = 7a + 2x × 1(x + a)
f(3 + 2) = ?​

Answer 1

Diketahui

f(x + a) = 7a + 2x × 1(x + a)

a = 2

x = 3

( 3 + 2 ) = 5

Ditanya

f(3 + 2 ) = ?

Jawab :

f(x + a) = 7a + 2x × 1(x + a)

f(3 + 2) = 7(2) + 2(3) × 1(3 + 2)

f(5) = 7(2) + 2(3) × 1(5)

f(5) = ( 7 + 7 ) + 2(3) × 1(5)

f(5) = 14 + 2(3) × 1(5)

f(5) = 14 + ( 2 + 2 + 2 ) × 1(5)

f(5) = 14 + ( 4 + 2 ) × 1(5)

f(5) = 14 + 6 × 1(5)

f(5) = 14 + 6 × ( 1 × 5 )

f(5) = 14 + 6 × 5

f(5) = 14 + ( 6 × 5 )

f(5) = 14 + 30

f(5) =

Kesimpulan

Jadi, hasil nya adalah

• › Dijawab

• Menentukan Hasil

• f( x + a ) = 7a + 2x × 1( x + a )
• f(3 + 2 ) = 7(2) + 2(3) × 1(3 + 2 )
• f(3 + 2 ) = ( 7 × 2 ) + ( 2 × 3 ) × ( 1 × ( 3 + 2 )
• f(3 + 2 ) = ( 14 ) + ( 6 × ( 1 × 5 )
• f(3 + 2 ) = ( 14 ) + ( 6 × 5 )
• f(3 + 2 ) = ( 14 + 30 )
• f(3 + 2 ) = 44 [✔️]

Kesimpulan ←

• Maka, Hasil = 44 [✔️]
