If functions f and g have domains Df and Dg respectively, then the domain of f/g is given by?

If functions f and g have domains Df and Dg respectively, then the domain of f/g is given by?

Explanation
  1. Intersection of Df and Dg: The function fg is defined only where both f and g are defined.

  2. Excluding zeros of g: The function fg is undefined where g(x)=0 because division by zero is not allowed.
