Question 347

The curve C C\,C with equation y=f(x)y = f(x)y=f(x) is shown on the diagram.

Cartesian axes with a curve C having a minimum in the first quadrant.

Given the minimum point of C C\,C is (1,e)(1, e)(1,e) and f′(x)=k(x−1)exf'(x) = k(x - 1)e^xf′(x)=k(x−1)ex, where k k\,k is a positive constant, find an equation for f(x)f(x)f(x) in terms of kkk.
