Question

A function f(x) is defined as f(x) = f(x – 2) - x(x + 2) for all the integer values of x and f(1) + f(4) = 0. What is the value of f(1) + f(2) + f(3) + f(4) + f(5) + f(6)?

Answer 1

answer :_91

because

f (3)=_14

f (5)=_15

f (6)=-42

given that f (2) +f (4)=0

then

f (2)+f (3)+f (4)f (5)+f (6)

= -42-15-14-0

=-91
