This would be (-1/x)+1 in the numerator, or (x-1)/x
\n" ); document.write( "the denominator would be 1-(2/x), or (x-2)/x
\n" ); document.write( "This is (x-1)/(x-2) ANSWER
\n" ); document.write( "Check.
\n" ); document.write( "Let x=3
\n" ); document.write( "f(3)=4/-5
\n" ); document.write( "f(-1/3)=(2/3)/(1/3)=2
\n" ); document.write( "(x-1)/(x-2) is -2/3/-(1/3)=2 \n" ); document.write( "

\n" );
