How many polynomial functions f of degree >=1 satisfy f(X2) = (f(X)) 2 =f (f(X)).
a) 1 b) 0 c) 2 d) more than 2

• only one
  i.e, when f(x)=x^2

• i m sry for my past post...
  the answer is a)= 1.
  only one polynomial function satisfy the condition whose degree=2.
  means f(x)=x^2

• d)more than 2..bcoz it depends on f(x).

• Sol:Let f(x)=x^2
  f(x^2)=x^4
  [f(x)]^2=x^4
  f(f(x))=x^4
  Only 1 sol.
