the domain for f%2Fg is the intersection of the domains of f and g, except for those numbers x such as that g%28x%29=0;
that is D%28f%29+%28intersection%29D%28g%29...-> {x|g(x) not+equal to 0}

Absolutely not. Consider two polynomial functions, and with real coefficients. The domain of each is all real numbers. The intersection of these two domains is itself the set of all real numbers. However the domain of excludes any real value such that .
