You can put this solution on YOUR website!

\n" ); document.write( "\n" ); document.write( "The domain of a rational function is all real numbers except any value for the variable that would cause the denominator to equal zero. Set the denominator equal to zero, solve for

. Then the domain is all real numbers except for the values in the solution set you just calculated.\r
