- | Webwork compares functions by plugging in some points and seeing if they match. This error means that Webwork failed when trying to compare the student's function/equation to the correct function/equation. This occurs when the numbers it tries to plug in to the correct function and the student's function are not in the domain of one or both functions. It can also occur due to computational limitations of WeBWorK's Perl-based arithmetic engine | + | Webwork compares functions by plugging in some points and seeing if they match.
