(f(fx)) = 2x +4 when f(X) = 1... how do I solve this

I have a few questions concerning functions... 1) X^3+64 2) 54p^3-16q^3 3) 2x^2-5x=3 4) 2x^2-8x=0 :confused: :confused:

Why would f(x) =pi/4x^3-sqrt2x+4 be classified as a polynomial? How would you determine the domain and range of y=x^4-4x^2? Assuming that the zeros of the function y=x^3+mx^2+nx+2 are integers how would you determine the values of m and n?? Thank you.

#1 Given f(x)-x^2-4 and g(x)=2x-1 how would you determine the value of (f+g)(3) and (f/g)(-1)? #2 If f(x)=x+2 and g(x)=x how would you find the value or values for which (fg)(x)=8? Thank you.
