Best ResponseYou've already chosen the best response.0The domain is the set of admissible values of x. In a rational function, the first thing to do is to see if there is a value of x that makes the entire denominator have a value of zero. If there is one that does that, it must be excluded from the domain because division by zero is undefined? Do you see such a value of x?

Best ResponseYou've already chosen the best response.0(y)/((4x^4)) is the answer to a simplify question I just saw that you posted in another thread. Forget about that and look at the question you posted in this thread.
