I'll get you started.
From the definition of )
we can say that \ =\ f(1)\ +\ f(2)\ +\ f(4))
.
But we don't know )
.
But \ =\ f(1)\ +\ f(2)\ +\ f(3))
.
But we don't know )
.
But \ =\ f(1)\ +\ f(2)\ +\ f(2))
.
Ah ha! \ =\ 2\ +\ 3\ +\ 3\ =\ 8)
.
Now you can go back and calculate and then once you have that value, you can calculate )
.
Good luck.
