\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=%286%29%2F%28x-8%29\"$ Start with the given function\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x-8=0\"$ Set the denominator equal to zero. Remember, dividing by 0 is undefined. So if we find values of x that make the denominator zero, then we must exclude them from the domain.\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=0%2B8\"$ Add 8 to both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=8\"$ Combine like terms on the right side\r

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since $\"x=8\"$ makes the denominator equal to zero, this means we must exclude $\"x=8\"$ from our domain\r
