\n" ); document.write( "Q65...

\n" ); document.write( "When x increases by 1 (from 1 to 2) the value of f(x) decreases by a factor of 3^2 = 9; i.e., it gets multiplied by a factor of 3^-2. That means k=2.

\n" ); document.write( "Then for x=1 we have

\n" ); document.write( "\"g%2A%283%5E-2%29+=+9\"
\n" ); document.write( "\"g%2F9+=+9\"
\n" ); document.write( "\"g+=+81\"

\n" ); document.write( "The function is

\n" ); document.write( "f(x) = 81(3^(-2x))

\n" ); document.write( "Q66...

\n" ); document.write( "Your statement of the question is not clear....
