how many polynomial functions f of degree greater than 1 satisfy f(x^2)=[f(x)]^2=f(x)?
a)more than 2
b)2
c)0
d)1

• Let f(x)=x;then f(x^2)=x^2,[f(x)]^2=x^2,will b equal when put"0".tk any polynomial it's true so ans is 0

• i think 1 f(x^2)
• 11 years agoHelpfull: Yes(9) No(9)
• ans is = 0

• 0 is the answer
• 11 years agoHelpfull: Yes(1) No(2)
• let f(x)=x^2(bcoz degree is
