\n" ); document.write( "Find the inverse:\r
\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=+2+%2B+1+%2F%28+-x-3%29\"$ ->I guess you have this\r
\n" ); document.write( "\n" ); document.write( "since
\n" ); document.write( " $\"f%28x%29=+y\"$ , we have\r
\n" ); document.write( "\n" ); document.write( " $\"y=+2+%2B+1+%2F%28+-x-3%29\"$ .........swap $\"x\"$ and $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=+2+%2B+1+%2F%28+-y-3%29\"$ .......solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x-2=++1+%2F%28+-y-3%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+-y-3=++1+%2F%28x-2%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+-y=++1+%2F%28x-2%29%2B3\"$ .............both sides multiply by $\"-1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+y=++-1+%2F%28x-2%29-3\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your inverse is: $\"f%5E-1%28x%29=+-1+%2F%28x-2%29-3\"$ \r
