In finding the domain of the rational function
r(x)=q(x)p(x) where p(x) and q(x) are polynomial functions, all real numbers are allowed for x except . . .The ones that would make the numerator zero. p(x)=0
The ones that would make the denominator zero. q(x)=0
The ones that would make the function zero. r(x)=0
The ones that would make the function undefined.
