The function \"f%28x%29=%283x-8%29%2F%284x%2B20%29\" is undefined for those values of x that \r
\n" ); document.write( "\n" ); document.write( "made the denominator zero. This values is \"4x%2B20=0\" => \"x=-5\", therefore \r
\n" ); document.write( "\n" ); document.write( "the domain of this function in set notation is: { x|x≠-5 }.
