You "read the value of f 1" by calling f 1.

NO. You were told to write *A* recursive function.
That's ONE recursive function. That's all you need.
g 0 = the maximum of [f 0] = what?
g n = the maximum of [f 0, f 1, ..., f (n-1), f n]
Now, DO YOU KNOW A FUNCTION THAT YOU CAN CALL TO COMPUTE
the maximum of [f 0, f 1, ..., f (n-1)]
Can you see HOW TO COMBINE that answer with f n to get the
final result you want? Is there a function MENTIONED IN
THE PROBLEM that could do this last step?
