Question

f(x) = f(x - 1) + f(x + 1), x is a whole number f(0) = 2 f(2) = 0 Question: What is the value of f(f(2))?

Answer 1

Answer:

The value of f(f(2)) = 2 .

Step-by-step explanation:

As given

The expression given in the question be .

f(x) = f(x - 1) + f(x + 1)

Where x is a whole number .

f(0) = 2 f(2) = 0

Now find out f(f(2)) .

f(f(2)) =  f(f(2- 1) + f(2 + 1))

    (As given f (2) = 0)

f(f(2)) =  f(0)

          = f(0 - 1) + f(0 + 1)

(As f (0) = 2)

f (f(2)) = 2

Therefore the value of f(f(2)) = 2 .
