Interactive FAQ
What is the domain of a rational function?
The domain is all real numbers except for the values that make the denominator zero.
What are vertical and horizontal asymptotes?
Vertical asymptotes occur where the function is undefined, and horizontal asymptotes occur as x approaches infinity.
