Hey /sci/
Braintlet here.
I was studying for my collage admission exam and i got stuck on this problem.
Any help?
$f(x)+x^{2}f(x-1)=1\quad\forall\quad x \in\mathbb{R}$ find $f(2)$
>>
For x =2 f(2) +22f(1) = 1

We need f(1), for x = 1:
f(1) + 1f(0) = 1

We need f(0), for x=0
f(0) + 0f(-1) = f(0) = 1

No just use f(0) =1 to find f(1) and than f(2)

22 is actually 2^2 = 4
