Find the domain of the rational function
\n" ); document.write( "h(x)= x-80 over x to the 3rd - 2x to the 2nd - 35x
\n" ); document.write( ".
\n" ); document.write( "Domain is all real numbers EXCEPT when 'x' makes the denominator zero.
\n" ); document.write( "Find those exceptions by setting the denominator to zero and solving for x:
\n" ); document.write( " $\"x%5E3-2x%5E2-35x+=+0\"$
\n" ); document.write( " $\"x%28x%5E2-2x-35%29+=+0\"$
\n" ); document.write( " $\"x%28x-7%29%28x%2B5%29+=+0\"$
\n" ); document.write( "x = {0, 7, -5}
\n" ); document.write( ".
\n" ); document.write( "Therefore, the domain is
\n" ); document.write( "\"All real numbers, except for 0, 7 and -5\"
\n" ); document.write( " \n" ); document.write( "

\n" );
