You can put this solution on YOUR website!
There are TWO restrictions here. First of all, the denominator must NEVER equal zero, so x cannot equal 3 or -3. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Secondly, because of the \"sqrt%28x%29\", x must be greater than or equal to zero!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, take the intersection of these two requirements, and you have all values greater than or equal to zero, except x=3. In interval notation, this would be\r
\n" ); document.write( "\n" ); document.write( "[0,3)U (3, inf)\r
