\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            To answer the question, you do not need to express the function   g^(-1)(x)   explicitly: it is an excessive unnecessary work.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            What you really need is to solve equation g(x) = -5 and find x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            It is just enough and can be done in couple of lines.\r

document.write( "    12x - 5 = -5   and implies   12x = 0,   x = 0.    \r\n" );
