f(x + 3) = 7x + 2
f(4) = a
x + 3 = 4
x = 4 - 3
= 1
f(1 + 3) = 7(1) + 2
f(4) = 7 + 2
f(4) = 9 --> a = 9
f(a) = f(9)
x + 3 = 9
x = 9 - 3 = 6
f(6 + 3) = 7(6) + 2
f(9) = 42 + 2
= 44

f(x+3)= 7x+2
misal x+3= p
maka, x= p-3
f(p)= 7(p-3)+2
f(p)= 7p-19
f(x)= 7x-19
jika f(4)= a
7(4)-19= a
28-19= a
a= 9
f(a) = 7(a)-19
f(9)= 7(9)-19
f(9)= 44
