Your curve must show: i)A straight line from (not through) the origin with unit gradient. (This correspond to the set of solutions for which x=y for ii)A curve with x=1 as asymptote for large y and y=1 as asymptote for large x. This curve intersects the straight line at x=e. This curve looks similar to the shape of y=1/x Solution by khaixiang |
