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
Jawaban:
2
Penjelasan dengan langkah-langkah:
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
