find the no. of polynomial for degree of x>+1 where f(x2)=f(x)2=f(f(x))

• f(x)=x^2
  f(x^2)=(x^2)^2=x^4
  (f(x))^2=(x^2)^2=x^4
  f(f(x))=f(x^2)=(x^2)^2=x^4
  so no of polinomial=1

• 1
  Let f(x) = x2
  f(x2)=[x2]2=x4
  (f(x))2=[x2]2=x4
  f(f(x))=f(x2)=[x2]2=x4

• 1 is the ans .
  Let assume f(x)=x2 and then solve u will get only one polynomial of degree grtr than 1

• why we are consider x2 .....not x3 reason plzzzz xplian clearly
