    Determine the domain of a rational function

    I am having a lot of trouble with this one...actually all of the problems that require me to find the domain of a rational function. If someone could walk me through how to solve one I would really appreciate it. Thank you!!!

    the domain is the set of input values (usually x-values) for which a function is defined. rational functions are only undefined where their denominator is zero. thus, to find their domain, solve for the denominator = zero, and say the domain is everything except those numbers

    Try posting one of the questions you can't do. Then someone can use that as the example you want.
