You can put this solution on YOUR website!
Inverse functions you mean.
\n" ); document.write( " $\"y=%28x-1%29%2F%28x%2B2%29\"$
\n" ); document.write( "Interchange x and y and solve for the new y, this is the inverse.
\n" ); document.write( " $\"x=%28y-1%29%2F%28y%2B2%29\"$
\n" ); document.write( " $\"x%28y%2B2%29=y-1\"$
\n" ); document.write( " $\"xy%2B2x=y-1\"$
\n" ); document.write( " $\"xy-y=-2x-1\"$
\n" ); document.write( " $\"y%28x-1%29=-2x-1\"$
\n" ); document.write( " $\"highlight%28y=%28-2x-1%29%2F%28x-1%29%29\"$ \n" ); document.write( "
