  3. But you did not say what you want to do with the two functions
    add them?
    multiply them ?

  4. another idea might be composition.

    (f◦g)(x) = f(g) = g^2+3g-1
    = (x^3+4x^2+1)^2+3(x^3+4x^2+1)-1
    = x^6+8x^5+16x^4+5x^3+20x^2+3

    (g◦f)(x) = g(f) = f^3+4f^2+1
    = (x^2+3x-1)^3+4(x^2+3x-1)^2+1
    = x^6+9x^5+28x^4+33x^3+4x^2-15x+4
