Let f(x) is a polynomial function of degree 5 with leading coefficient equals to one and f(4) = 0 if curves y=|f(x)| and y=f(|x|) are same then f(1) is equal to ?

Question

Let f(x) is a polynomial function of degree 5 with leading coefficient equals to one and f(4) = 0 if curves y=|f(x)| and y=f(|x|) are same then f(1) is equal to ?

Karan · Answer

f(x)=(x-4)².x.(x+4)1 |f(x)|=f|(x)| x€R f(5)=(5-4)1.5.(5+4)²=405 Therefore f of 5 is equal to 405 I hope you got it

Utsav Desai · Answer

@Karan But how do we come to know that f(x)=(x-4)².x.(x+4)1. That is the main doubt with me. Other websites are also giving same solutions, but no one is explaining why...
