$\large\color{blue}{    f(x)=x^2+4x^3  }$
$\large\color{blue}{    g(x)=x^2-4x^3  }$

sure this is the information? maybe one sign is missing?

no thats all

solomonzelman · Answer

$\large\color{blue}{    f(x)=x^2+4x^3 \ g(x) = -x^2 -4x^3 }$
this is when the g(x) is a reflection of f(x) across the x-axis.

Not when  $\large\color{blue}{  g(x) = x^2 -4x^3 }$
