### Re: BdMO Regional 2021 Higher Secondary P8

I didn't think about $f$ could be bijective. :cry: :cry: :cry: So it gave me a weird solution, a huge one in fact. you are much better than me i $f(f(x))=x$ reminded me of involution and i knew that the function is bijective but i thought the question wanted $f(x)$ in $x$ terms so i gave the ans $0...
