Quiz(46/100)
[tex] \: [/tex]
f(x + 2) = 6x + 3
f(2) = ...​

Jawaban:

2

Penjelasan dengan langkah-langkah:

f(x + 2) = 6x + 3

misal x + 2 = a

a = 6x + 3

6x = a - 3

x = 1/6 a - 1/2

lalu kita masukkan ke fungsi

f(a) = 6(1/6 a - ½) + 3

f(a) = a

f(x} = x

f(2) = 2

f(x + 2) = 6x + 3

f ( x + 2 ) = 6 ( x - 2 ) + 3

f ( x + 2 ) = 6x - 12 + 3

f ( x + 2 ) = 6x - 9

f(2) = 6 ( 2 ) - 9

f(2) = 12 - 9

f(2) = 3
