Find the domain of the rational function.
\n" ); document.write( "f(x)= x+5/ (x^2-64x)
\n" ); document.write( "function is undefined when denominator=0
\n" ); document.write( "x^2-64=0
\n" ); document.write( "x^2=64
\n" ); document.write( "x=±√64=±8
\n" ); document.write( "Domain: (-∞,-8) U (-8,8) U (8,∞)
\n" ); document.write( "{x|x≠-8, x≠8} \n" ); document.write( "
\n" );
