Web154 Find the domains of rational functions . A vertical asymptote represents a value at which a rational function is undefined, so that value is not in the domain of the function. A reciprocal function cannot have values in its domain that cause the denominator to equal zero. In general, to find the domain of a rational function, we need to determine which … WebGiven a rational function, find the domain. Set the denominator equal to zero. Solve to find the x -values that cause the denominator to equal zero. The domain is all real numbers except those found in Step 2.
