The only rule is that the argument be greater than zero.
\n" ); document.write( "\"9-8x-x%5E2%3E0\"
\n" ); document.write( "Graphing the function,
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C2%2C-6%2C6%2C9-8x-x%5E2%29\"
\n" ); document.write( "The argument is positive between the values of \"-9\" and \"1\" so the domain is,
\n" ); document.write( "(\"-9\",\"1\")
\n" ); document.write( "Here's a graph of the function.
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C2%2C-6%2C6%2Cln%289-8x-x%5E2%29%29\"
