You can put this solution on YOUR website!
Assume that \"y=2%5E%28x%5E2%29-5\", solve this equation for x:\"y-5=2%5E%28x%5E2%29\"=>\r
\n" ); document.write( "\n" ); document.write( "\"ln%28y-5%29=x%5E2%2Aln2\"=>\"x=sqrt%28ln%28y-5%29%2Fln2%29\", interchange x and y and get the \r
\n" ); document.write( "\n" ); document.write( "inverse function:\"f%5E-1%28x%29=sqrt%28ln%28x-5%29%2Fln2%29\". The domain of this function is:\r
\n" ); document.write( "\n" ); document.write( "(5, \"infinity\"). The value x=-11 is not included in its domain for this value\r
\n" ); document.write( "\n" ); document.write( "the function \"f%5E-1%28x%29\" is undefined.
